TY - JOUR T1 - Uncertainty in experimental techniques for measuring sediment erodability. AN - 67909570; 16640316 AB - There are many experimental methods currently utilized to measure sediment erodability and stability. When utilizing any of the available methods or devices to characterize erodability, one must understand the inherent uncertainty associated with each technique in relation to the application or expected measurement need. In addition, while some uncertainties are unique to a particular measurement device or technique, other uncertainties arise from variation in sediment conditions or properties. Several widely used devices and techniques are discussed with respect to their uncertainties and applicability for certain measurements. Finally, suggestions will be made on how to reduce uncertainty and manage it in model development.

Because of the high contrast in electrical conductivity between the salt and surrounding sediments, Gemini is an attractive target for electromagnetic interrogation. Using a broadband magnetotelluric (MT) sensor package developed at the Scripps Institution of Oceanography, data in the period band of 1 to 3000 s were collected at 42 sites in a series of profiles over Gemini, one of which was directly over a linear ridgelike salt feature striking roughly northwest-southeast and another orthogonal to it. These two profiles reveal that the strongest MT response arises when the electric field is oriented northeast-southwest. We test the suitability of 2D inversion of these data for recovering the true salt structure by examining inversions of both actual data and synthetic 3D MT responses derived from the seismically inferred salt volume. Occam inversions of the northeast-southwest component result in resistivity images that generally agree with the seismic data, whereas inversions of the complementary component yield significantly poorer fidelity. Disagreement is greatest (1-2 km) along the salt sides and base. Depth errors for top of salt are less than 500 m. Although thin, deep salt (<1 km thick at 5 km depth) is not well resolved, the inversions reveal a resistive basement and a shallow subseabed environment rich in electrical heterogeneity that is weakly, if at all, suggested by the seismic data. A notable exception is a correlation between a previously uninterpreted seismic reflector and the base of a shallow resistivity anomaly whose presence is consistent with gas accumulation near the hydrate stability zone.

This article ascertains the requirement of upscaling and presents a scheme to upscale the transmissivity in the near-well region for 2-D steady flow, which extends the approach of Gomez-Hernandez & Journel (1994) to the near-well region with radial flow. Several synthetic fields with different stochastic models are chosen to check the efficiency of this scheme. Both flow and transport simulations are carried out in finite confined heterogeneous aquifers to evaluate the results. It is shown that the proposed method improves the ability in predicting well discharge or recharge and solute transport at the coarse scale.

As an example of this interaction, the highly-overpressured sedimentary rocks of the Gulf of Mexico are cut by numerous active but seismically "quiet" normal faults that have acted as conduits for large volumes of fluid. The South Eugene Island Block 330 Field, offshore Louisiana, contains hydrocarbons and brine that flowed up a set of aseismic faults into a section of Pliocene-Pleistocene reservoir sands at fluxes that are orders of magnitude higher than allowed by the ambient fault permeability. The 'A' Fault, adjacent to the reservoirs, is the locus of paleotemperature anomalies indicative of the discontinuous ascent of hot fluids in the past. Discontinuous present-day fluid flow in the fault system has also been imaged on successive dip-filtered 3D seismic surveys, which show a migrating pulse of highly-pressured fluid within a splay of the 'A' Fault; the high fluid pressure is corroborated by drilling records. Relatively high effective stress in the fault system at depths shallower than about 2.5 km limits fluid flow up the faults. Fluid ascent in, and lateral escape from, the faults requires slip events to produce the necessary fracture network. Fluid flow and fault movement are probably coupled in the growth fault system at South Eugene Island Block 330.

This is illustrated by the ductile, brittle and dissolution characteristics of a deformed Paleozoic limestone in the Basin and Range province, where superimposed compression, extension, and folding within an outcrop only one square kilometer in extent have produced a complex suite of deformational structures. In addition to numerous natural fractures of various types, larger-scale structural heterogeneities include: 1) thrust faults with meter-scale displacement and local folding of bedding, 2) pods of disrupted bedding, related to thrusting, up to ten meters along strike, 3) normal faults in several orientations, filled locally with calcite mineralization up to several tens of centimeters thick, 4) meter-scale caves along some of the faults, and 5) folding on the scale of tens of meters. Smaller-scale heterogeneities include chert nodules and beds, and pervasive calcite-filled fractures, commonly occurring as en echelon conjugate arrays and as bed-normal extension fractures. Although the cherts are typically less than a meter in scale, they offer significant local mechanical contrasts in bedding, and are pervasively fractured. The strata are composed of alternating layers of dark-gray and light-gray limestone which accommodated strain in significantly different ways reflecting different mechanical properties: darker rock is more brittle and typically more heavily fractured. Many of the structures are large enough to influence subsurface fluid flow. Similar features are present in other examples of deformed limestones throughout the Basin and Range province.

However, their differences in chemical and mechanical properties dictate important differences in the probability of fracturing and the potential effects of the fractures on reservoirs. For example, although laboratory tests show that limestones and sandstones have similar strengths (i.e., they fail compressively at similar pressures), limestones are more compliant, requiring larger amounts of strain before reaching the failure limit. Thus, under the same conditions, limestones should have fewer fractures than sandstones. This is the case in examples from the Holbrook Basin of Arizona, where fractured beds of Coconino Sandstone are interbedded with more sparsely fractured beds of Kaibab Limestone, even though the beds are of similar thickness. Likewise, because limestones are readily soluble, hairline fractures are commonly healed immediately after fracturing, and therefore the bulk mechanical properties of limestones are commonly not significantly altered by the presence of small fractures. If the host limestone is contaminated by clay or organic matter, however, the calcite-filled fractures are more susceptible than the host rock to failure and fracture reactivation, as well as to dissolution. This is illustrated by examples from the Lisburne Limestone and the Austin Chalk. Fractures in limestone may also provide initial pathways for significant secondary dissolution of the host rock itself, leading to cavernous porosity that is rare in sandstones. Finally, the permeability along limestone fractures may be more susceptible to damage than sandstone fractures during the pressure cycles associated with production from a reservoir.

Most of this evidence has been used uncritically and out of context, and does not form a mutually supporting, scientifically defensible framework. Plausible evidence for subsurface dissolution is limited to the water-bearing Magenta Member in drillhole WIPP-33. The remaining evidence is more readily interpreted as primary sedimentary features. Thinning and thickening of Rustler strata, and lateral lithologic variations from halite to mudstone, are primary depositional patterns related to lateral sedimentary facies changes across the WIPP site rather than evidence for post-depositional dissolution. Some of the evidence offered in support of dissolution is inherited from early interpretations made prior to the knowledge of modern evaporite depositional environments, and prior to the existence of definitive exposures of the rock in the WIPP shafts which show undissolved, primary depositional features. Holes drilled to investigate the subsurface strata at the sites of proposed sinkholes do not support karsting of the Rustler Formation. Extrapolation of the known karst features in Nash Draw eastward to the WIPP site is unwarranted.

Early studies found sodium chloride brine along the draw axis above halite of the Salado Formation, with the brine flowing toward and into the Pecos River. The draw was interpreted as the consequence of erosion, solution, and fill. Later studies report solution of sulfate units of the Rustler, yielding more complicated surficial structures. More drillhole logs are now available, showing that the eastern margin of Nash Draw (Livingston Ridge) overlies the position where the elevation of upper Salado halite changes, as does the thickness across the upper Salado and the elevation of overlying units. These elevation changes reflect dissolution of Salado halite. Depressions along Livingston Ridge result from subsidence that has caused recent regrading of arroyos. At Laguna Grande de la Sal, elevations of the top of Salado halite indicate a depression under the lake, and lower halite south of the lake is associated with elongate valley-like depressions as well as rounded basins. The movement of brine at depth may be directed along this surface. Surface karst features in the southeastern arm of Nash Draw develop on and within sulfate beds of the Rustler Formation and surficial gypsite. Collapse sinks and coalescing collapse in small karst valleys appear to show some evolutionary trends based on period since erosion exposed sulfate beds. Vertical-walled collapse sinks without fill are young, while karst valleys are older. These features are developed along stratigraphic trends. Some of the recharge in this sulfate-dominated environment discharges year-round in local springs, indicating fluid storage within the system. Alluvium in sinks and karst valleys are proposed as part of the storage system.

Alunite is particularly important not only because it is a byproduct of sulfuric acid cave genesis, but because it contains telling isotopic signatures of sulfur, oxygen, hydrogen, potassium, and argon. Alunite has been reliably dated using the (super 40) Ar/ (super 39) Ar method yielding the timing of sulfuric-acid speleogenesis for Carlsbad Cavern, Lechuguilla Cave, and other sulfuric-acid caves as well as uplift and canyon incision rates for the Guadalupe Mountains. The repeatability of the (super 40) Ar/ (super 39) Ar results was demonstrated from analyses of alunite aliquots processed three different ways: 1) non-chemical alunite separation by simple gravity-method in water, 2) chemical separation using HF, 1 & 2 were not encapsulated for irradiation; and 3) encapsulation of HF-treated aliquots for irradiation. In addition to the chronology, negative sulfur isotope values for the alunite strongly point to a microbial-related process, and both alunite and natroalunite occur as micrometer-sized cube-like rhombs, an indicator of a low temperature origin of these large caverns. Larger a dimensions of the unit-cells of relatively well-formed alunite from the caves (determined by X-ray diffraction) are similar to those of synthetic alunites produced in the laboratory at <1000 degrees C, and also support a low-temperature origin. Stable isotope values of the oxygen and hydrogen in the alunite have potential to generate more accurate values for the temperature and isotopic character of water in which the caves were formed. Timing of speleogenesis determined by (super 40) Ar/ (super 39) Ar dating of alunite shows this process was active as far back as approximately 12 Ma and slowly migrated eastward for at least 8-9 Ma up to 3-4 Ma ago. Rio Grande Rift faulting and tilting of the Guadalupe block during this period is probably the eastward-driving mechanism. If sulfuric-acid speleogenesis is taking place today, it is most likely happening east of the Guadalupe Mountains in the subsurface.

Two significant transgressive freshening events deposited thin carbonate beds, each about 8 m thick. The Culebra Dolomite Member is the more permeable of the carbonate units. One of the geological factors influencing permeability is the presence or absence of halite cements in both fractures and other porosity. These cements underlie halite in the halite pan to mudflat deposits in a higher unit, and they confirm an earlier prediction that diagenetic halite would fill Culebra porosity near the depositional center. The Magenta Dolomite Member follows the basic Culebra pattern, with halite-filled porosity in a drillhole nearer the depositional center. Cores recently obtained corroborate interpretations that mudstones in the Rustler were generally deposited without significant halite, or it was removed by syndepositional dissolution; they are not residues after later dissolution of halite. A laminar gray claystone underlying the Culebra is continuous across the study area, overlying mudflat as well as halite pan deposits. It indicates that the underlying mudstones are not dissolution residues. The uppermost mudstone-halite bed of the Rustler in a new drillhole shows a division between lower halite pan deposits and upper mudflat deposits that is also reflected in more distal mudflat deposits of the entire unit. These findings increase confidence that mudstones will yield additional information about the history of the mudflat to halite has beds of the Rustler. One new core from the Tamarisk Member shows brecciation consistent with earlier predictions that halite has been dissolved in a limited area within this unit. The lower Rustler now reveals wider distribution of halite cements, which are not easily distinguished in available geophysical logs. These data help refine ideas about the effects of halite cements and dissolution on porosity and on geochemistry of water or brine recovered from Rustler carbonates. Halite in these units also limits vertical Culebra recharge by limiting permeability, and its very presence indicates that little fresh water can be percolating into and through halitic beds.

As part of the compliance certification process with the U.S. Environmental Protection Agency (EPA), groundwater monitoring programs have been established to measure changes in water level as well as chemical and physical properties of the water. The monitoring network currently consists of 63 wells situated in and around the WIPP vicinity. Of these, 49 are completed to the Culebra Dolomite Member of the Permian Rustler Formation, the most transmissive hydrologic unit in the WIPP vicinity. Comparison of Culebra water-level records with precipitation records indicates that there is a local area of recharge in the vicinity of WIPP, namely Nash Draw ( approximately 8 km west of WIPP). Recharge, in turn, appears to be driven by intense rainfall events (>60 mm) of short duration (<48 hrs). The limited response observed in Culebra wells spread over the WIPP site to such rainfall events does not support the suggestion that karst exists in the vicinity of WIPP, except in Nash Draw.

This paper reviews the experimental and analytical work performed to date on large-scale spills of LNG. Specifically, experiments on the dispersion of LNG, as well as experiments of LNG fires from spills on water and land are reviewed. Explosion, pool boiling, and rapid phase transition (RPT) explosion studies are described and discussed, as well as models used to predict dispersion and thermal hazard distances. Although there have been significant advances in understanding the behavior of LNG spills, technical knowledge gaps to improve hazard prediction are identified. Some of these gaps can be addressed with current modeling and testing capabilities. A discussion of the state of knowledge and recommendations to further improve the understanding of the behavior of LNG spills on water is provided.

The surface soils (0-15 cm) were intentionally contaminated with Brazilian sludge (containing super(232)Thorium and other radionuclides) approximately 40 years ago, in order to simulate the conditions resulting from a nuclear weapons accident. Site grading consisted of manually raking or machine disking the sludge. The majority of the radioactivity was found in the top 15 cm of soil, with retention ranging from 69 to 88%. Two models, a compartment diffusion model and leach rate model, were evaluated to determine their capabilities and limitations in predicting radionuclide behavior. The migration rates of actinium were calculated with the diffusion compartment and the leach rate models for all sites, and ranged from 0.009 to 0.1 cm/yr increasing with depth. The migration rates calculated with the leach rate models were similar to those using the diffusion compartment model and did not increase with depth (0.045-0.076, 0.0 cm/yr). The research found that the physical and chemical properties governing transport processes of water and solutes in soil provide a valid radionuclide transport model. The evaluation also showed that the physical model has fewer limitations and may be more applicable to this environment.

Combining the theoretical framework of 'learning by doing' and developments in 'learning by searching' with the fields of organizational learning and institutional economics offers a complete methodological framework to examine the underlying capital cost trajectory when developing electricity cost estimates used in energy policy planning models. Sensitivities of the learning rates for global wind and solar photovoltaic technologies to changes in the model parameters are tested.

To fully understand the results of pilot scale tests and to accurately predict scale-up performance through CFD modeling, accurate rate expressions are needed to describe coal char combustion under these unconventional combustion conditions. In the work reported here, the combustion rates of two pulverized coal chars have been measured in both conventional and oxygen-enriched atmospheres. A combustion-driven entrained flow reactor equipped with an optical particle-sizing pyrometry diagnostic and a rapid-quench sampling probe has been used for this investigation. Highvale subbituminous coal and a high-volatile eastern United States bituminous coal have been investigated, over oxygen concentrations ranging from 6 to 36 mol% and gas temperatures of 1320- 1800 K. The results from these experiments demonstrate that pulverized coal char particles burn under increasing kinetic control in elevated oxygen environments, despite their higher burning rates in these environments. Empirical fits to the data have been successfully performed over the entire range of oxygen concentrations using a single-film oxidation model. Both a simple nth-order Arrhenius expression and an nth-order Langmuir-Hinshelwood kinetic equation provide good fits to the data. Local fits of the nth-order Arrhenius expression to the oxygen-enriched and oxygen-depleted data produce lower residuals in comparison to fits of the entire dataset. These fits demonstrate that the apparent reaction order varies from 0.1 under near-diffusion-limit oxygen-depleted conditions to 0.5 under oxygen-enriched conditions. Burnout predictions show good agreement with measurements. Predicted char particle temperatures tend to be low for combustion in oxygen-depleted environments.

Emerging BioMicroNanotechnologies (Gourley, 2005) have the potential to provide accurate, realtime, high throughput screening of tumor cells without invasive chemical reagents. These techniques are critical to advancing early detection, diagnosis, and treatment of disease. Using a new technique to rapidly assess the properties of cells flown through a nanolaser semiconductor device, we discovered a method to rapidly assess the respiratory health of a single mammalian cell. The key discovery was the elucidation of biophotonic differences in normal and transformed (cancer) mouse liver cells by using intracellular mitochondria as biomarkers for disease. This technique holds promise for detecting cancer at a very early stage and could nearly eliminate delays in diagnosis and treatment.

Where the geologic media (e.g., rock, soil) is fractured, gravity-driven fingers within the fractures may lead to extremely rapid vertical migration of waterborne contaminants. We designed analog fractures to facilitate the competition between viscous, gravity, and capillary forces that is expected to control finger behavior, then conducted an extended experimental investigation to observe and measure finger behavior. Results show that the spatially variant two-dimensional nature of fracture geometry leads to different behavior than is reported for the related problem of gravity-driven fingers in porous media. Observations of finger behavior are presented, along with a simple scale analysis used to relate the key measures of finger velocity, finger width, and fingertip length. We also present a series of illustrative experiments designed to guide future research.

Their formulation uses the MSU/DOE fatigue data base to develop a CLD with detailed S-N information at 13 R-values. This diagram is the most detailed to date, and it includes several loading conditions that have been poorly represented in earlier studies. Sutherland and Mandell have used this formulation to analyze typical loads data from operating wind farms and the failure of coupons subjected to spectral loading. The detailed CLD used in these analyses requires a significant investment in materials testing that is usually outside the bounds of typical design standards for wind turbine blades. Thus, the question has become: How many S-N curves are required for the construction of a CLD that is sufficient for an 'accurate' prediction of equivalent fatigue loads and service lifetimes? To answer this question, the load data from two operating wind turbines and the failure of coupons tested using the WISPERX spectra are analyzed using a nonlinear damage model. For the analysis, the predicted service lifetimes that are based on the CLD constructed from 13 R-values are compared to the predictions for CLDs constructed with fewer R-values. The results illustrate the optimum number of R-values is 5 with them concentrated between R-values of -2 and 0.5, or -2 and 0.7.

European Desalination Society. AN - 17214686; 6891662 AB - The worldwide need for fresh sources of drinking water continues to outstrip supply while the resources necessary to develop new supply remain limited. The best solution to this dilemma is the coordination of research efforts on an international basis. The Desalination and Water Purification Roadmap presents a summary of the water supply challenges facing the United States, and suggests areas of research and development that may lead to technological solutions to these challenges. These solutions have international application at the same time that innovation is occurring internationally. This Roadmap is a living document - updates to the Roadmap may be made on a regular basis to ensure that it remains current and relevant. The Roadmap is also complemented by a series of additional documents, created as a result of meetings to be held, focused on: - - x Defining discrete research projects and priorities based on the information contained within this Roadmap; - x Identifying regulatory issues related to the implementation of desalination and water purification technologies, and developing potential solutions where conflicts are found; - x Identifying, evaluating, and quantifying the impaired water resources to better assess the impact that desalination and water purification technologies may have on water supplies; - x Generating plans to accelerate the commercialization of desalination and water purification technologies developed as a result of this Roadmap. This Roadmap cannot exist in a vacuum - technology development must be undertaken with the context of the product's end-use in mind. The goal of this process is to: - - x Develop a consensus and direction to guide investments for the creation of new water purification technologies; - x Identify the roles that various sectors of the economy (e.g., national government agencies, the private sector, educational and non-profit organizations) can play in the creation of new water purification technologies; and - x Develop an expert group to review alternative water purification technologies.

2006-015370 AB - The Barton Springs segment of the Edwards Aquifer, located in Austin, Texas, is an area of rapid urbanization with increasingly observable effects on the water quality and quantity of the springs. To help mitigate the impacts of the urban growth, future management scenarios have been proposed that involve changing development rates and patterns for areas overlying and adjacent to the aquifer. The future of Barton Springs has become the subject of heated political debate involving the interests of developers, environmentalists, and property rights activists. Complicating matters is the fact that the aquifer and Barton Springs are home to two endangered salamander species. To help alleviate current and future conflict, we present a prototype decision support system (DSS) that addresses the issue of aquifer sustainability by merging existing spatially-variant, hydrogeological, urbanization, and GIS models into a systems dynamics framework. The DSS is developed and tested within the context of stakeholder deliberations with input from developmental, environmental, property rights, and government interests. Structured within a user-friendly interface, the DSS allows scenario and hypothesis testing, bracketing and optimization of possible outcomes, and real-time interactive feedback concerning current and future states of the system. A key innovation is the integration of spatially variable data (impervious cover, urban-enhanced recharge, and stream setbacks in the proto-type model) into the systems dynamics framework to examine heterogeneous urban growth patterns, spatially changing aquifer recharge characteristics due to urban development, together with economic and ecologic decision analysis. The proto-type addresses spring discharge and concerns of decreased well yields while future work will also incorporate stream discharge and ground and surface-water quality.

This difficulty has led to the development of various modeling tools to support the decision making process. These tools are typically based on a systems dynamics approach that brings together disparate yet connected systems, such as water resources and economics, by using a lumped-parameter "commodity balance" approach and are designed to examine the consequences of various decisions through facilitated deliberation and aggregation of both hard and soft data. While these approaches represent significant advancement over past efforts, and current efforts have become increasingly sophisticated and useful, none of them are able to assess spatially variable consequences of different policy decisions. For example, will urban development in one area have a higher or lower impact than urban development in another area? This study addresses the spatial limitations of the systems dynamics approach by combining spatially aggregated physical models, in the form of a MODFLOW groundwater model, with a systems dynamics model developed in the POWERSIM environment. This is a collaborative research effort between Sandia National Laboratories and The University of Texas at Austin and uses the Barton Springs segment of the Edwards Aquifer in Austin, Texas as its test case. The process involves the creation of a "data exchange manager" that serves as the central communication hub for the two groundwater simulation models, linking the input and output of each model to a centralized geodatabase. The geodatabase in turn is accessed by analysts, decision makers, and stakeholders via a user-friendly graphical user interface. The data exchange manager is designed in a modular fashion to permit the incorporation of additional types of models beyond the example models, MODFLOW and POWERSIM. The final structure provides a higher fidelity modeling approach that utilizes real-time information to facilitate and assist in the policy development and decision making process. The integration of the modeling structure into the decision making process is also presented.

A main concern with HLNW storage is groundwater seepage into constructed drifts, or storage cavities. An analytical model proposed by Philips, et al. (1989) predicts flow diversion around drifts due to the presence of a capillary barrier resulting in a drift shadow beneath the drift. The amount of drift diversion and the outflow location are controlled by the drift diameter, capillary pressure, and fracture aperture. To verify the presence of the capillary barrier and its resulting drift shadow and to validate Philips's model, two centimeter-scale test cells with different, continuous fracture apertures were constructed from TSw rock samples. Fractures were located throughout the middle of the rock samples, parallel to the rock faces and normal to the drift axes. A potassium iodide (KI) solution was introduced into the test cells and outflow collected at different lateral locations at the base of the cells and inside the drift cavities. X-ray absorption imaging visualized and captured pictures of KI solution movement through the fracture. While the preliminary results from three tests show the difficulties in comparing flow behavior between heterogeneous media and the predicted behavior in a homogenous media, they also demonstrated the presence of the drift shadow and flow diversion away from the drift.

The colloidal particles employed in this work are 1.0, 0.11, and 0.043 mu m diameter fluorescent carboxylate-modified microspheres, injected at various flow rates through parallel-plate fractures with either Plexiglas as both surfaces, or Plexiglas as one surface and a mineral cleavage plane or crystal face as the second surface. Transport experiments conducted using physically and chemically homogeneous synthetic Plexiglas fractures are used to better understand the dispersion of colloids in fractured media. Specifically, the Peclet number of each experiment is varied by changing colloid size, flow rate, and fracture length. Experiments are run under conditions where colloid attachment and remobilization are thought to be negligible. Breakthrough data are fit using a particle-tracking algorithm run inversely with PEST and the effective dispersion rate for each experiment is estimated. As expected from theoretical calculations, results indicate that in these fractures, colloid dispersion due to the velocity gradient is evident, but fully developed Taylor conditions are not realized. Log effective dispersion is found to increase linearly with the log of the Peclet number. These numerical results may be used to differentiate between tailing effects due to dispersive processes and those due to attachment and remobilization when colloids are transported through mineral-Plexiglas fractures.

A modelling exercise, aimed at predicting field behaviour, was divided in three parts. In Part A, predictions for both the total water inflow to the tunnel as well as the water pressure changes induced by the boring of the tunnel were required. In Part B, predictions for local field variables, such as temperature, relative humidity, stresses and displacements at selected points in the bentonite barrier, and global variables, such as the total input power to the heaters were required. In Part C, predictions for temperature, stresses, water pressures and displacements in selected points of the host rock were required. Ten Modelling Teams from Europe, North America and Japan were involved in the analysis of the test. Differences among approaches may be found in the constitutive models used, in the simplifications made to the balance equations and in the geometric symmetries considered. Several aspects are addressed in the paper: the basic THM physical phenomena which dominate the test response are discussed, a comparison of different modelling results with actual measurements is presented and a discussion is given to explain the performance of the various predictions.

Humic acids (HA), known to strongly bind to actinides and which may be generated by the degradation of organic materials present in the waste, may influence the performance of the WIPP. This work presents experimental results on the effect of WIPP brines, ERDA-6 and GWB, and of the WIPP engineered barrier, Premier Chemicals magnesium oxide, on the solubility of HA. In the absence of MgO, a portion of HA initially precipitates, but a constant concentration of HA remains in solution: over a 60 day period of time, at least 290+ or -10 mg/L HA can remain soluble in de-ionized (DI) water, 30+ or -4 mg/L in 95% ERDA-6, and 31+ or -4 mg/L in 95% GWB. For solutions initially containing from 0 to 400 mg/L HA, the ratio of the initial HA concentration and the soluble HA concentration is 1.3 in DI water, 13 in 95% ERDA-6, and 11 in 95% GWB. In the presence of MgO, all HA precipitate within 60 days in systems with a high liquid-to-solid ratio (10.0 g/g) or a low ratio (2.4 g/g). This phenomenon is due to HA precipitation and/or sorption on the surface of MgO.

In insulator-based dielectrophoresis (iDEP) insulating microstructures produce non-uniform electric fields to drive DEP in microsystems. This article describes the performance of an iDEP device in removing and concentrating bacterial cells, spores and viruses while operated with a DC applied electric field and pressure gradient. Such a device can selectively trap particles when dielectrophoresis overcomes electrokinesis or advection. The dielectrophoretic trapping behavior of labeled microorganisms in a glass-etched iDEP device was observed over a wide range of DC applied electric fields. When fields higher than a particle-specific threshold are applied, particles are reversibly trapped in the device. Experiments with Bacillus subtilis spores and the Tobacco Mosaic Virus (TMV) exhibited higher trapping thresholds than those of bacterial cells. The iDEP device was characterized in terms of concentration factor and removal efficiency. Under the experimental conditions used in this study with an initial dilution of 1x105 cells/ml, concentration factors of the order of 3000x and removal efficiencies approaching 100% were observed with Escherichia coli cells. These results are the first characterization of an iDEP device for the concentration and removal of microbes in water.

AN - 19458188; 7023870 AB - Physical, chemical and biological properties are the ultimate information of interest for chemical compounds. Molecular descriptors that map structural information to activities and properties are obvious candidates for information sharing. In this paper, we consider the feasibility of using molecular descriptors to safely exchange chemical information in such a way that the original chemical structures cannot be reverse engineered. To investigate the safety of sharing such descriptors, we compute the degeneracy (the number of structure matching a descriptor value) of several 2D descriptors, and use various methods to search for and reverse engineer structures. We examine degeneracy in the entire chemical space taking descriptors values from the alkane isomer series and the PubChem database. We further use a stochastic search to retrieve structures matching specific topological index values. Finally, we investigate the safety of exchanging of fragmental descriptors using deterministic enumeration.

Significant progress has been made on the improvement of titanium's bioactivity by coating its oxide surface with calcium phosphates and bioactive molecules. Here, we report on the coating of titanium with a poly( l-lysine)-calcium phosphate hybrid material with a nanoscale texture. This hybrid coating was grown by first nucleating seed crystals of calcium phosphate, directly on the Ti surface and then exposing this surface to solutions containing Ca super(2+), PO sub(4) super(3-), and poly( l-lysine). The resultant hybrid coating was characterized by electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis, X-ray photoelectron spectroscopy, and elemental analysis. This material contained 14% by weight poly( l-lysine), and this organic component decreased greatly the dimensions of the surface features, thus enhancing surface area relative to the inorganic control. The highly textured hybrid material was more susceptible than the control to acidic and enzymatic degradation. The amino acid cysteine was covalently linked to the hybrid material, demonstrating the potential of this coating for further functionalization. These hybrid coatings may prove useful in enhancing the bioactivity of titanium.

Although many studies have been conducted to assess the consequences and risks of potential LNG spills, the increasing importance of LNG imports suggests that consistent methods and approaches be identified and implemented to help ensure protection of public safety and property from a potential LNG spill. For that reason, the U.S. Department of Energy (DOE), Office of Fossil Energy, requested that Sandia National Laboratories (Sandia) develop guidance on a risk-based analysis approach to assess and quantify potential threats to an LNG ship, the potential hazards and consequences of a large spill from an LNG ship, and review prevention and mitigation strategies that could be implemented to reduce both the potential and the risks of an LNG spill over water.

Time-dependent calculations are performed implicitly by regarding each time step as a steady-state problem in pseudo-time. The method of artificial compressibility is used to solve the flow equations. The solution mesh adaptation method performs local mesh refinement using an incremental Delaunay algorithm and mesh coarsening by means of edge collapse. Mesh movement is achieved by modeling the computational domain as an elastic solid and solving the equilibrium equations for the stress field. The solution adaptation method has been validated by comparison with experimental results and other computational results for low Reynolds number flow over a shedding circular cylinder. Preliminary validation of the mesh movement method has been demonstrated by a comparison with experimental results of an oscillating airfoil and with computational results for an oscillating cylinder.

This presentation investigates and illustrates formal procedures for assessing the uncertainty in the probability that a safety system will fail to operate as intended in an accident environment. Probability theory and evidence theory are introduced as possible mathematical structures for the representation of the epistemic uncertainty associated with the performance of safety systems, and a representation of this type is illustrated with a hypothetical safety system involving one weak link and one strong link that is exposed to a high temperature fire environment. Topics considered include (1) the nature of diffuse uncertainty information involving a system and its environment, (2) the conversion of diffuse uncertainty information into the mathematical structures associated with probability theory and evidence theory, and (3) the propagation of these uncertainty structures through a model for a safety system to obtain representations in the context of probability theory and evidence theory of the uncertainty in the probability that the safety system will fail to operate as intended. The results suggest that evidence theory provides a potentially valuable representational tool for the display of the implications of significant epistemic uncertainty in inputs to complex analyses.

Igneous intrusion (or 'volcanism') of a geologic repository at Yucca Mountain for radioactive waste is one disruptive event that has a probability with a range of uncertainty that straddles this regulatory criterion and is considered directly in performance assessment calculations. A self-sustained nuclear chain reaction (or 'criticality') is another potentially disruptive event to consider, although it was never found to be important when evaluating the efficacy of radioactive waste disposal since the early 1970s. The thesis of this article is that the consideration of the joint event-volcanism and criticality-occurring in any 10,000-year period following closure can be eliminated from performance calculations at Yucca Mountain. The probability of the joint event must be less than the fairly well-accepted but low probability of volcanism. Furthermore, volcanism does not 'remove' or 'fail' existing hydrologic or geochemical constraints at Yucca Mountain that tend to prevent concentration of fissile material. Prior to general corrosion failure of waste packages, the mean release of fissile mass caused by a low-probability, igneous intrusive event is so small that the probability of a critical event is remote, even for highly enriched spent nuclear fuel owned by the U.S. Department of Energy. After widespread failure of packages occurs, the probability of the joint event is less than the probability of criticality because of the very small influence of volcanism on the mean fissile mass release. Hence, volcanism plays an insignificant role in inducing criticality over any 10 super(4)-yr period. We also argue that the Oklo reactors serve as a natural analogue and provide a rough bound on probability of criticality given favorable hydrologic or geochemical conditions on the scale of the repository that is less than 0.10. Because the product of this bound with the probability of volcanism represents the probability of the joint event and the product is less than 10 super(-4) in 10 super(4) yr, consideration of the joint event can be eliminated from performance calculations.

For this work, fine particles with aerodynamic diameter between 10 nm and 1 mm were examined. A constant solid-fuel thermal input of 8 kW was maintained. The combustion products were cooled from 1200 to 420DGC during passage through the 4.2 m long reactor to simulate the temperatures experienced in the convection pass of a boiler. Fine particle number densities, mass concentrations, and total integrated number and mass concentrations at the reactor exit were determined using a scanning mobility particle sizer. The fine particle number concentrations for cofiring were much higher than those achieved with dedicated coal combustion. However, the total integrated mass concentration of particles remained essentially constant for all levels of cofiring from 0% coal to 100% coal. The constant mass concentration is significant because pending environmental regulations are likely to be based on particle mass rather than particle size.

This short communication represents the FORUM's position on the validation of numerical fire models. These models are increasingly being used on the fire protection engineering community, and have the potential for a significant impact with the increasing acceptance of performance based fire codes. The FORUM position is to require verification and validation of these models. Activities should include; code verification to identify and reduce coding errors, calculation verification to establish appropriate model usage, and model validation to provide a quantitative assessment of the predictive capabilities of a model. Peer-reviewed documentation of these activities should be published in the open literature. The importance of verification of models for fire phenomenon, and an overview of these activities, are discussed.

We conclude that CMT is adequate for visualization of transport experiments if the right conditions exist. Namely, 1) not much more than one-order-of-magnitude range in concentration data is needed for the study, 2) the pore space in the samples are greater than approximately 2-50 mu m, depending on the sample size and system setup; 3) the sample is fine- grained enough so that a representative elemental volume (REV) can be contained by a 2-10 mm diameter sample, and 4) the transport process is slow enough that significant changes do not occur within the 25-50 min (and possibly less in the future) needed to collect data for one three-dimensional image. Absorption edge difference imaging (AEDI) in association with CMT is introduced as a method to enhance pore-space visualization. We successfully imaged the pore space in a low-porosity granodiorite, diorite and fine-grained granite cores and a higher- porosity soil aggregate sample. We found that the pore space important to transport in the core samples was smaller than what we were able to visualize with CMT. We also made rudimentary associations of minerals with pore-space location.

Data on discharge, pH, organic carbon (total), N- NH sub(4) super(+)+organic N (total), NH sub(4) super(+) (dissolved), N-NO sub(2) super(-)+N- NO sub(3) super(-) (dissolved), phosphorus (total), and P-orthophosphate (dissolved) came from six USGS stations - Lobatos, Taos Junction, Otowi, San Felipe, Isleta and Bernardo - ranging from the Colorado-New Mexico border to about 80 km below Albuquerque, NM. Kendall's S and Seasonal Kendall's S' were used to measure trend, and ANOVA and Tukey's multiple comparison test were used to analyze spatial differences between stations. Temporal trend analyses show widespread decreases in N and P concentrations at most stations, likely due to improvements in sewage treatment and dilution from increasing discharge. N- NO sub(2) super(-)+N-NO sub(3) super(-) (dissolved) and total nitrate load increases at Isleta and Bernardo, likely due to improved nitrification in sewage treatment and to increasing human population. Spatial analyses show large increases for most parameters at Isleta. All parameters show decreases again at Bernardo, about 50 km downstream from Isleta, except for N-NO sub(2) super(-)+N-NO sub(3) super(-) (dissolved), which continues to increase. Urbanization in the Albuquerque area significantly impacts downstream river nutrient levels.

An optimal sensor configuration minimizes the expected fraction of the population at risk. We formulate this problem as a mixed-integer program, which can be solved with generally available solvers. We find optimal sensor placements for three test networks with synthetic risk and population data. Our experiments illustrate that this formulation can be solved relatively quickly and that the predicted sensor configuration is relatively insensitive to uncertainties in the data used for prediction.

Conventional analysis methods work well for processing objective information. However, in practical situations, much or most of the data available are subjective. Also, there are potential resultant pitfalls where conventional analysis might be unrealistic, such as improperly using event tree and fault tree failure descriptions where failures or events are soft (partial) rather than crisp (binary), neglecting or misinterpreting dependence (positive, negative, correlation), and aggregating nonlinear contributions linearly. There are also personnel issues that transcend basic human factors statistics. For example, sustained productivity and safety in critical operations can depend on the morale of involved personnel. In addition, motivation is significantly influenced by "latent effects," which are pre-occurring influences. This paper addresses these challenges and proposes techniques for subjective risk analysis, latent effects risk analysis and a hybrid analysis that also includes objective risk analysis. The goal is an improved strategy for risk management. JF - SAFE 2005.

Specifically, the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 established requirements for each community water system serving more than 3,300 people to conduct an assessment of the vulnerability of its system to a terrorist attack or other intentional acts. Integral to evaluating system vulnerability is the threat assessment, which is the process by which the credibility of a threat is quantified. Unfortunately, full probabilistic assessment is generally not feasible, since there is insufficient experience and/or data to quantify the associated probabilities. For this reason, an alternative approach is proposed predicated on Markov latent effects (MLE) modeling, which provides a framework for quantifying imprecise subjective metrics through possibilistic or fuzzy mathematics. Here, the MLE approach is introduced and demonstrated within the context of water supply system threat assessment.

AN - 67734310; 15824586 AB - The diminished response of thermoluminescent phosphors over time is a well-documented challenge to thermoluminescent dosimetry. Wide ranges in fading rates for various phosphor types have been reported, making it necessary for many external dosimetry programs to perform individual studies on thermoluminescent fade. Sandia National Laboratories currently uses the Thermo 8802 LiF:Mg,Ti thermoluminescent dosimeter (TLD) in its personnel external dosimetry program. Doses received in the field are calculated by applying a fade algorithm published by the manufacturer to TLD readings. Since the algorithm was established by characterizing the diminished response of a TLD similar to the 8802, Sandia chose to model its fade study after the analysis done by Thermo. As a result, the parameters of each experiment were comparable, and data from the two studies were compared to determine whether or not the current algorithm should be modified specifically for use at Sandia. Cards were irradiated using an internal Sr/Y source, and pre- and post-irradiation fading rates were monitored over a period of 18 wk. While significant fading was demonstrated, results closely matched those found in the original Thermo study.

Aluminum coordination is octahedral in solution, and tetrahedral in feldspar crystals. Whether this change in coordination can occur on feldspar surfaces as part of the dissolution mechanism has been debated. Molecular orbital calculations were performed on aluminosilicate clusters with a few surrounding water molecules to partially account for solvation effects at the feldspar-water interface. The calculations on both fully-relaxed and partially-constrained clusters suggest that the energy difference between (super [4]) Al and (super [6]) Al where both are linked to three Si-tetrahedra (i.e., Q (super 3) Al) in the feldspar structure, is small enough to allow for the conversion of Q (super 3) (super [4]) Al to Q (super 3) (super [6]) Al in a hydrated layer of feldspar, prior to the release of Al ions to the aqueous solution. The introduction of a few water molecules to the clusters introduced the possibility of multiple optimized geometries for each Al coordination, with energy differences on the order of several hydrogen bonds. The calculation of activation energies and transition states between Q (super 3) (super [4]) Al, Q (super 3) (super [5]) Al, and Q (super 3) (super [6]) Al was complicated by the introduction of water molecules and the use of fully-relaxed aluminosilicate clusters. Calculated isotropic shifts for Q (super 1) (super [6]) Al, Q (super 2) (super [6]) Al, and Q (super 3) (super [6]) Al suggest that the (super [6]) Al observed on aluminosilicate glass surfaces using (super 27) Al CP MAS-NMR is Q (super 1) (super [6]) Al and therefore formed as part of the dissolution process. The formation of (super [6]) Al in situ on a feldspar surface (as opposed to re-precipitation from solution) has significant implications for the dissolution mechanism and surface chemistry of feldspars.

AN - 67509884; 15763355 AB - The presence of surface-active solutes such as organic acids and bases may have a profound influence on the transport of organic liquid contaminants through their impact on the constitutive relationship of capillary pressure vs. saturation. This relationship is a function of the interfacial tension and wettability of the system, which, in turn, depend on the pH and the concentration of organic acids and bases that are present. This study examines the impact of pH and the concentration on the interfacial tension, contact angle, and capillary pressure of systems consisting of tetrachloroethylene, water, and quartz containing either octanoic acid or dodecylamine. In general, the ionic form of the solute tended to remain in the aqueous phase and reduced the capillary pressure through its impact on the interfacial tension and contact angle; on the other hand, the neutral form of the solute partitioned into the organic liquid phase and had a lesser impact on the capillary pressure for the same total mass of solute. A comparison of these data with data generated in previous research in similar systems where o-xylene was the organic liquid showed that the trends are analogous. Thus, the behavior of these two solvent systems seems to be driven primarily by the aqueous phase speciation of the solute, and the differences between the capillary pressure relationships for the two systems could be attributed to the pure system interfacial tension.

The original peat layer thickness data include two types of censored observations: the physical and measurement limits. To avoid assigning values arbitrarily to them, the indicator approach was used, in which all observations are transformed into either 0 or 1 depending upon the exceedence of any given threshold. In this study, peat-soil thickness values are estimated using blocks with different sizes (i.e., change of support). Indicator kriging is applied to construct conditional cumulative distribution functions (ccdf) defines peat layer thickness at centers of estimation blocks. From the point ccdf obtained, an optimal estimate of peat layer thickness at each block is obtained by taking the mean of the point ccdf. The ccdf value beyond the maximum threshold is modeled by the linear model as it fits well to the original cumulative distribution of data. The choice of the extrapolation model needs to be guided by available information. The total peat-soil volume is estimated simply summing up the volume at each block (optimal thickness X area of the block). The estimated volumes are almost constant when the block size less than 200 m is used, indicating that the mean of the point ccdf at the center of the block can be used as the representative value of the block. When much larger block sizes are used, the ccdf at the center of the block cannot be used to estimate the block value. In such a case, the block ccdf need to be derived using different approaches such as stochastic simulation. The estimated total peat-soil volume within the investigation boundary at the Bacho site is 2.14 X 10 (super 7) m (super 3) , when the block size smaller than 200 m are used. Using the average organic carbon content value measured at the site, the total organic carbon storage is estimated 1.22 X 10 (super 9) kg C.

In 1996, a major flood on the Gila River aggraded the Colorado River Channel by 1.3 m along a distance approximately 10 km downstream from the confluence. Two million cubic feet of sediment were subsequently dredged from the channel to provide the capacity needed to prevent floods. This study details a survey conducted to determine the minimum discharge rate needed to maintain the active channel and transport excess sediment to prevent a reoccurrence. The survey involved a detailed study of the sediments along a 30 kilometer long stretch of the river around Yuma Arizona using the Adjustable Shear Stress Sediment Erosion and Transport (ASSET) Flume, used to measure insitu sediment erosion properties at various shear stresses at different flow conditions and depth. Twenty-six core samples along a stretch of the river were analyzed insitu to determine flow parameters while particle sizes and size distribution where determined in the laboratory using the Malvern Mastersizer. The cores contain coarse sediments, clay, and organic materials with the organic materials more prevalent at the surface of the stream sediment. The sediments analyzed from various locations within the study area were observed to have varying flow parameters and bulk properties. The plots obtained from the data show a general trend of a decrease in erosion rate and an increase in shear stress with increase in depth. However, sediments in areas with abundant organic materials draping the sediment tend to have a higher shear stress near the sediment surface. Samples with interstratified gravels, sand, clay and organic materials which reduce sediment erodibility were found to exist primarily along the river bank and at mid-channel bars on the river channel. Also, the critical shear stress required to erode and transport sediments generally increased upstream from the dam to near where the river passes through a granite bedrock constriction at the city of Yuma then gradually diminished in value.

However, to fully exploit the advanced computational power provided by today's supercomputers, innovative parallel algorithms are needed. We demonstrate the use of Jacobian-free Newton-Krylov (JFNK) within the Newton-Raphson method to reduce memory and processing requirements on high-performance computers. We also demonstrate the use of physics-based preconditioners, which are often necessary when using JFNK since no explicit Jacobian matrix is ever formed. We apply JFNK to simulate enhanced in situ bioremediation of a NAPL source zone, which entails highly coupled geochemical and biodegradation reactions. The algorithm's performance is evaluated and compared with conventional solvers and preconditioners. We found that JFNK provided substantial saving in memory (i.e. 30-60%) on problems utilizing up to 512 processors on LANL's ASCI Q. However, the performance based on wallclock time was less advantageous, coming out on par with conventional techniques. In addition, we illustrate deficiencies in physics-based preconditioner performance for biogeochemical transport problems with components that undergo significant sorption or form a local quasi-stationary state.

Two detection schemes were investigated: (i) a direct assay in which fluorescently labeled toxins were captured directly by the antibody array and (ii) a competition assay that employed unlabeled toxins as reporters for the quantification of native toxin in solution. In the direct assay, fluorescence measured at each array element is correlated with labeled toxin concentration to yield baseline binding information (Langmuir isotherms and affinity constants). Extending from the direct assay, the competition assay yields information on the presence, identity, and concentration of toxins. A significant advantage of the competition assay over reported profiling assays is the minimal sample preparation required prior to analysis because the competition assay obviates the need to fluorescently label native proteins in the sample of interest. Sigmoidal calibration curves and detection limits were established for both assay formats. Although the sensitivity of the direct assay is superior to that of the competition assay, detection limits for unmodified toxins in the competition assay are comparable to values reported previously for sandwich- format immunoassays of antibodies arrayed on planar substrates. As a demonstration of the potential of the competition assay for unlabeled toxin detection, we conclude with a straightforward multiplexed assay for the differentiation and identification of both native S. aureus enterotoxin B and tetanus toxin C fragment in spiked dilute serum samples.

As the electromagnetic pulse propagates along the transmission line, it is subject to impedance by the dielectric properties of the media along the transmission line (e.g., air, water, and sediment), reflection at dielectric discontinuities (e.g., air-water or water-sediment interface), and attenuation by electrically conductive materials (e.g., salts and clays). Taken together, these characteristics provide a basis for integrated stream monitoring, specifically, concurrent measurement of stream stage, channel profile, and aqueous conductivity. Requisite for such application is a means of extracting the desired stream parameters from measured TDR traces. Analysis is complicated by the fact that interface location and aqueous conductivity vary concurrently and multiple interfaces may be present at any time. For this reason a physically based multisection model employing the S sub(11) scatter function and Debeye parameters for dielectric dispersion and loss is used to analyze acquired TDR traces. Here we explore the capability of this multisection modeling approach for interpreting TDR data acquired from complex environments, such as encountered in stream monitoring. A series of laboratory tank experiments was performed in which the depth of water, depth of sediment, and conductivity were varied systematically. Comparisons between modeled and independently measured data indicate that TDR measurements can be made with an accuracy of +/-3.4 x 10 super(-3) m for sensing the location of an air-water or water-sediment interface and +/-7.4% of actual for the aqueous conductivity.

Using a set of sparse pairwise atomic distance constraints (such as those obtained from chemical cross-linking, FRET, or dipolar EPR experiments), the algorithm performs an exhaustive search of secondary structure element packing conformations distributed throughout the entire conformational space. The end result is a set of distinct protein conformations, which can be scored and refined as part of a process designed for computational elucidation of transmembrane protein structures.

AN - 67532215; 15704246 AB - We report the development of a hand-held instrument capable of performing two simultaneous microchip separations (gel and zone electrophoresis), and demonstrate this instrument for the detection of protein biotoxins. Two orthogonal analysis methods are chosen over a single method in order to improve the probability of positive identification of the biotoxin in an unknown mixture. Separations are performed on a single fused-silica wafer containing two separation channels. The chip is housed in a microfluidic manifold that utilizes o-ring sealed fittings to enable facile and reproducible fluidic connection to the chip. Sample is introduced by syringe injection into a septum-sealed port on the device exterior that connects to a sample loop etched onto the chip. Detection of low nanomolar concentrations of fluorescamine-labeled proteins is achieved using a miniaturized laser-induced fluorescence detection module employing two diode lasers, one per separation channel. Independently controlled miniature high-voltage power supplies enable fully programmable electrokinetic sample injection and analysis. As a demonstration of the portability of this instrument, we evaluated its performance in a laboratory field test at the Defence Science and Technology Laboratory with a series of biotoxin variants. The two separation methods cleanly distinguish between members of a biotoxin test set. Analysis of naturally occurring variants of ricin and two closely related staphylococcal enterotoxins indicates the two methods can be used to readily identify ricin in its different forms and can discriminate between two enterotoxin isoforms.

From these results, a simple 1D model of velocities can be extracted and used to validate, refine, or correct the detailed dipole-sonic data or provide a warning of discrepancies.

Electroporation is the permeabilization of the cell membrane due to an applied electric field. As a function of the field amplitude and duration, the permeabilization can be reversible or irreversible. Over the last decade, reversible electroporation has been intensively pursued as a very promising technique for the treatment of cancer. It is used in combination with cytotoxic drugs, such as bleomycin, in a technique known as electrochemotherapy. However, irreversible electroporation was completely ignored in cancer therapy. We show through mathematical analysis that irreversible electroporation can ablate substantial volumes of tissue, comparable to those achieved with other ablation techniques, without causing any detrimental thermal effects and without the need of adjuvant drugs. This study suggests that irreversible electroporation may become an important and innovative tool in the armamentarium of surgeons treating cancer.

AN - 67561563; 15794599 AB - We present theoretical performance estimates for nanotube optoelectronic devices under bias. Current-voltage characteristics of illuminated nanotube p-n junctions are calculated using a self-consistent nonequilibrium Green's function approach. Energy conversion rates reaching tens of percent are predicted for incident photon energies near the band gap energy. In addition, the energy conversion rate increases as the diameter of the nanotube is reduced, even though the quantum efficiency shows little dependence on nanotube radius. These results indicate that the quantum efficiency is not a limiting factor for use of nanotubes in optoelectronics.

Industry and laboratory research efforts are now focusing on integration of thermal energy storage as a viable means to enhance dispatchability of concentrated solar energy. One option to significantly reduce costs is to use thermocline storage systems, low-cost filler materials as the primary thermal storage medium, and molten nitrate salts as the direct heat transfer fluid. Prior thermocline evaluations and thermal cycling tests at the Sandia National Laboratories' National Solar Thermal Test Facility identified quartzite rock and silica sand as potential filler materials. An expanded series of isothermal and thermal cycling experiments were planned and implemented to extend those studies in order to demonstrate the durability of these filler materials in molten nitrate salts over a range of operating temperatures for extended time frames. Upon test completion, careful analyses of filler material samples, as well as the molten salt, were conducted to assess long-term durability and degradation mechanisms in these test conditions. Analysis results demonstrate that the quartzite rock and silica sand appear able to withstand the molten salt environment quite well. No significant deterioration that would impact the performance or operability of a thermocline thermal energy storage system was evident. Therefore, additional studies of the thermocline concept can continue armed with confidence that appropriate filler materials have been identified for the intended application.

For a solution method to be viable, it must account for this relationship by being accurate in both space and time. This research presents a unique method for solving the time-dependent ADE that does not discretize the derivative terms but rather solves the equation analytically in the space-time domain. The method is computationally efficient and numerically accurate and addresses the common limitations of numerical dispersion and spurious oscillations that can be prevalent in other solution methods. The method is based on the improved finite analytic (IFA) solution method [Lowry TS, Li S-G. A characteristic based finite analytic method for solving the two-dimensional steady-state advection-diffusion equation. Water Resour Res 38 (7), 10.1029/2001WR000518] in space coupled with a Laplace transformation in time. In this way, the method has no Courant condition and maintains accuracy in space and time, performing well even at high Peclet numbers. The method is compared to a hybrid method of characteristics, a random walk particle tracking method, and an Eulerian-Lagrangian Localized Adjoint Method using various degrees of flow-field heterogeneity across multiple Peclet numbers. Results show the IFALT method to be computationally more efficient while producing similar or better accuracy than the other methods.

The microfluidic immunoassays are performed by gel electrophoretic separation and quantitation of bound and unbound antibody or antigen. To retain biological activity of proteins and maintain intact immune complexes, nondenaturing polyacrylamide gel electrophoresis conditions were investigated. Both direct (noncompetitive) and competitive immunoassay formats are demonstrated in microchips. A direct immunoassay was developed for detection of tetanus antibodies in buffer as well as diluted serum samples. After an off-chip incubation step, the immunoassay was completed in less than 3 min and the sigmoidal dose-response curve spanned an antibody concentration range from 0.17 to 260 nM. The minimum detectable antibody concentration was 0.68 nM. A competitive immunoassay was also developed for tetanus toxin C-fragment by allowing unlabeled and fluorescently labeled tetanus toxin C-fragment compete to bind to a limited fixed concentration of tetanus antibody. The immunoassay technique described in this work shows promise as a component of an integrated microfluidic device amenable to automation and relevant to development of clinical diagnostic devices.

Although there have been recent advances in both experimental and computational methods for predicting protein- protein interactions, we are only beginning to see a confluence of these techniques. In this paper, we describe a very general, high-throughput method for predicting protein-protein interactions. Our method combines a sequence- based description of proteins with experimental information that can be gathered from any type of protein-protein interaction screen. The method uses a novel description of interacting proteins by extending the signature descriptor, which has demonstrated success in predicting peptide/protein binding interactions for individual proteins. This descriptor is extended to protein pairs by taking signature products. The signature product is implemented within a support vector machine classifier as a kernel function. RESULTS: We have applied our method to publicly available yeast, Helicobacter pylori, human and mouse datasets. We used the yeast and H.pylori datasets to verify the predictive ability of our method, achieving from 70 to 80% accuracy rates using 10-fold cross-validation. We used the human and mouse datasets to demonstrate that our method is capable of cross- species prediction. Finally, we reused the yeast dataset to explore the ability of our algorithm to predict domains.

The overall system, referred to as mu ChemLab, has a modular design that provides for reliability and flexibility and that facilitates rapid assembly, fluid and microchip replacement, troubleshooting, and sample analysis. Components include two independent separation modules that incorporate interchangeable fluid cartridges, a 2-cm-square fused-silica microfluidic chip, and a miniature laser-induced fluorescence detection module. A custom O-ring sealed manifold plate connects chip access ports to a fluids cartridge and a syringe injection port and provides sample introduction and world-to-chip interface. Other novel microfluidic connectors include capillary needle fittings for fluidic connection between septum-sealed fluid reservoirs and the manifold housing the chip, enabling rapid chip priming and fluids replacement. Programmable high-voltage power supplies provide bidirectional currents up to 100 mu A at 5000 V, enabling real-time current and voltage monitoring and facilitating troubleshooting and methods development. Laser-induced fluorescence detection allows picomolar (10 super(-11) M) detection sensitivity of fluorescent dyes and nanomolar sensitivity (10 super(-9) M) for fluorescamine-labeled proteins. Migration time reproducibility was significantly improved when separations were performed under constant current control (0.5-1%) as compared to constant voltage control (2-8%).

In spite of this, internal pressures in both nations to obtain the ability to fight a 'limited nuclear war' are increasing. Such a strategy would probably require a new class of law-yield battlefield nuclear weapons. This article, focused primarily on India's dilemma with nuclear strategy, first surveys Indian and Pakistani academic & official statements on the utility of battlefield nuclear weapons, then demonstrates that the military utility of these weapons is very limited in the South Asian context. The article concludes that an India-Pakistan restraint regime for battlefield nuclear weapons is needed & explores how such a regime might be structured & monitored. 1 Table, 25 References.

The WIPP is the U.S. Department of Energy's deep geological repository for transuranic and mixed wastes resulting from the nation's defense programs. The WIPP repository is located 655 m below ground surface in bedded halite of the Permian Salado Formation, which underlies the Rustler and Culebra. Culebra transmissivities (T's) in the vicinity of the WIPP vary over six orders of magnitude, with higher T's (log (sub 10) T (m (super 2) /s) > -5.4) reflecting zones of well-interconnected fractures. We develop, test, and refine a conceptual model for predicting fracture zones within the Culebra. We define three regional-scale controls on Culebra fracturing, including the dissolution of salt from below the Culebra, the presence of halite above and below the Culebra, and overburden thickness. We also identify two local-scale controls on Culebra fracture zones including fracture-filling cements and localized deformation due to ductile flow of the mudstone that underlies the Culebra. The spatial distribution of the regional-scale controls is easily predicted. However, the influence of local controls can only be uniquely identified in hydraulic test data. A drilling program initiated in 2003 tests aspects of this conceptual model and leads to minor revisions of our conceptual understanding of the geologic controls on fracturing in the Culebra.

The sol- gel encapsulation of cells is achieved at room temperature and neutral pH. Furthermore, use of sodium silicate as precursor avoids generation of alcohol that can be detrimental to cells in contrast to the traditional alkoxide sol-gel encapsulation process. Moraxella spp. cells engineered to express recombinant organophosphorus hydrolase (OPH) on the cell surface were encapsulated and OPH enzymatic activity was measured for paraoxon hydrolysis. Kinetic parameters (K sub(m) and V sub(max)) as well as pH behavior of surface-expressed OPH were determined to evaluate the effect of encapsulation. Cells encapsulated by the sodium silicate method displayed higher activity retention compared to those by the traditional alkoxide process. Time-course studies over a 2-month period indicate that immobilization through the sodium silicate process led to a reduction in activity of similar to 5% as compared to similar to 30% activity reduction in case of free cells in buffer indicating that immobilization leads to stabilization, a key parameter in biosensor development.

For safety reasons, only simulated smoke sources are permitted in these certification tests. To provide insight into smoke detection certification in cargo compartments, this research investigates the morphology, transport and optical properties of actual and simulated smoke sources. Experimental data show the morphology of the particulate in smoke from flaming fires is considerably different from simulated smoke. Although the detection of smoldering fires is important as well, only a qualitative assessment and comparison of smoldering sources was possible; therefore, efforts were concentrated on the quantitative comparison of smoke from flaming fires and smoke generators. The particulate for all three different flaming fires was solid with similar morphological properties. Simulated smoke was composed of relatively large liquid droplets, and considerably different size droplets can be produced using a single machine. Transport behavior modeling showed that both the actual and simulated smoke particulates are sufficiently small to follow the overall gas flow. However, actual smoke transport will be buoyancy driven due to the increased temperature, while the simulated smoke temperature is typically low and the release may be momentum driven. The morphology of the actual and simulated smoke were then used to calculate their optical properties. In contrast to the actual smoke from a flaming fire, which is dominated by absorption, all of the extinction for the simulated smoke is due to scattering. This difference could have an impact on detection criteria and hence the alarm time for photoelectic smoke detectors since they alarm based on the scattering properties of the smoke.

Water containing red dye followed by blue-green dye was ponded in a small horizontal zone (about 0.5 by 0.5 m) above a vertical outcrop (about 4 by 2.5 m). The red dye lagged behind the wetting front due to slight adsorption, thus allowing both the wetting front and dye fronts to be observed in time at the outcrop face. After infiltration, vertical slices were excavated to the midpoint of the infiltrometer, exposing the wetting front and dye distribution in a quasi three-dimensional manner. At small scale, wetting front advancement was influenced by the multitude of local capillary barriers within the deposit. However, at the scale of the experiment, the wetting front appeared smooth with significant lateral spreading, twice that in the vertical, indicating a strong anisotropy due to the pronounced horizontal layering. The dye fronts exhibited appreciably more irregularity than the wetting front, as well as the influence of preferential flow features (a fracture) that moved the dye directly to the front, bypassing the fresh water between. To illustrate the ability of equivalent homogeneous media models to capture the behavior of the wetting front, we performed numerical simulations using equivalent homogeneous media with isotropic, anisotropic, and moisture- dependent anisotropic properties. Those containing anisotropy matched the experimental data best.

AN - 1416690416; 2013-059786 AB - With the purpose of attaching meaning to the waveforms imaged by reverse-time migration, we obtain an expression for the output of such an algorithm over a simple subsurface model of a dipping interface. We invoke the cross-correlation imaging condition and make extensive use of the stationary phase approximation to analyze the migrated image. Our result quantifies the meaning of the amplitudes output from reverse-time shot-profile migration and should have relevance for direct migration of passive seismic data and frequency-swept source signals. A numerical example of reverse-time migration supports our theoretical results.

These empirical relationships provide a physical basis for numerical modeling and allow us to investigate the effect of fluid pressure. The presence of more than one stress path complicates the prediction of fluid pressure from seismically derived interval velocities since the relationship between seismic velocity and pore pressure is multi-valued.

Geologically realistic earth models, containing spatially-correlated random variations in material properties, are readily generated with a wavenumber-domain algorithm. Calculated synthetic seismic data clearly show numerous effects associated with scattering of compressional, shear, and surface waves by the randomly distributed perturbations.

Coalbed methane production from Cretaceous and Tertiary coals on the New Mexico side increased sharply in 1999 following the construction of a pipeline to deliver the gas from this portion of the basin. Currently there are approximately 400 wells operated by El Paso Production Company on privately owned land in Colfax County, New Mexico, and Las Animas County, Colorado. Coal seams of the Upper Cretaceous Vermejo Formation and the Cretaceous-Tertiary Raton Formation are the current targets for development, although some of the clastic units within this interval are likely gas charged and could become exploration targets in the future. Relatively modest gas production from most wells is acceptable given the high success rate and shallow depth ( approximately 2000 feet) of the producing interval. However, marked differences in production rates, decline behavior, and water chemistry among wells in this area suggest complex hydrologic and geologic controls which preclude a simple coalbed methane reservoir description. Wells in the southwest portion of the lease are, by far, the best producers with several wells producing more than one million cubic feet of gas per day (> 1 MMCFGD) and having an average monthly production of 8 million cubic feet of gas per well. The typical well elsewhere in this lease produces less than 100,000 cubic feet of gas per day (< 100 MCFGD) and has a monthly production around 2.5 million cubic feet of gas. In addition, many of the best wells do not show the characteristic gas incline/water decline curves associated with the early production history of typical coalbed methane wells, and in fact produce very little water as compared to other wells on the lease. A number of wells throughout the lease exhibit a double peak in gas production--one occurring fairly early in the production history, and another after a period of dewatering. The first peak may represent drainage of free gas stored within the natural fracture and cleat system of the reservoir, with the second peak due to desorption of methane from the coal matrix.

Analyses of field data, core, geophysical data (well logs and seismic) and production profiles, suggest that regions with different production characteristics can be delineated based on geologic controls. These include, but are not limited to; large-scale structures, faulting, fractures, hydrodynamics, sedimentology, and present-day topography/depth of erosion. Production patterns vary across the Vermejo Park Ranch relative to location with respect to the Vermejo Park Anticline. Large-scale structures, such as this anticline, have generated local fracture patterns that are superimposed over the regional fracture set. Large structures can also create unique present-day topographic/depth of erosion patterns. For example the Vermejo Park and Tercio Anticlines are breached anticlines with surface exposures of the Pierre Shale. Thus the entire vertical column of the coalbed methane play is exposed at the surface around these structures, altering the influx and outflow of meteoric waters into the local coal reservoirs. Such structures influence the hydrodynamic flow and production patterns across the basin. Production around the Vermejo Park Anticline can be divided into quadrants. Coalbed methane production from the SW quadrant has fresher water, more N-S fractures, lower water cut, higher reservoir pressures, greater gas production and a conventional hyperbolic gas decline curve compared to the NE quadrant which has a higher water cut, lower reservoir pressures, lower production rates and typical reverse-decline coalbed methane production curves. The smaller scale geologic controls of fluid flow directionality relative to these production domains will also be discussed.

Chemical modeling of the system included acquisition of data representative of the proposed repository and near-field host rock environments; development of an aqueous Pitzer database and demonstration of its capability; modeling of processes important in the in-drift environment (evaporation, dilution, and deliquescence) and their effect on water chemistry; and abstraction of model results to produce total system performance assessment look-up tables used directly in the safety case. The data and methods to be presented will emphasize the consistency and integration of the resulting in-drift chemical modeling, from model development to implemented abstraction.

The resulting specific discharge from the alternate flow models (AFMs) is in the range of 0.51 to 0.653 m/year, significantly lower than the value of 1.3 m/year for the base case flow model (BFM). The flow paths resulting from the AFMs are generally deeper and more southerly than those from the BFM. The fraction of each flow path in volcanics versus the alluvium for the AFMs is greater than that for the BFM. This is important because in this transport model the volcanics are represented as a dual-porosity medium with low effective porosities (and resultant high fluid flow velocities), significant matrix diffusion, and retardation in the matrix, while the alluvium is represented by a single porosity medium with much higher effective porosities (with resultant lower fluid flow velocities), and retardation but no matrix diffusion. Colloid-facilitated transport is important in both media. For conservative radionuclides, the median transport time (time required for 50% of the input mass to breakthrough at the boundary to the accessible environment at 18 km) for the AFMs ranges from 6500 to 9100 years, as compared to the value of 705 years for the BFM. Thus the AFMs lead to significantly slower transport of the radionuclides as compared to BFM. This shows that the form of the flow model is an important source of uncertainty in transport predictions. Comparison of AFMs with and without matrix diffusion in the volcanics shows that matrix diffusion leads to significant retardation of the radionuclides, and this mechanism is more pronounced at the lower velocities encountered in AFMs. The median transport time for a moderately sorbing radionuclide such as Np using an AFM is about 75,000 years, considerably greater than the corresponding value of about 26,000 years for BFM. In conclusion, the AFMs lead to median transport times significantly longer than that for the BFM.

The repository, which opened in March 1999, is located at a subsurface depth of 655 m in the Salado Fm., a Permian bedded-salt formation. The repository will eventually comprise 56 disposal rooms, each 91.4 m long by 9.14 m wide by 3.96 m high, arranged in eight seven-room panels. After filling the rooms and access drifts and installation of panel closures, creep closure of the salt will crush the waste containers in most cases and encapsulate the waste. Anoxic corrosion of Fe- and Al-base metals and microbial consumption of cellulosic, plastic, and rubber (CPR) materials could produce significant quantities of gas in the WIPP. Radiolysis will not produce gas at rates comparable to those at which anoxic corrosion and microbial activity could. If significant gas production occurs, it would affect, and would be affected by, other processes and parameters in the repository. These include: (1) the rates and extent of brine inflow and outflow, (2) the rates and extent of room closure, and (3) the chemical conditions that affect the actinide source term. MgO is being emplaced in the WIPP to decrease the solubilities of the actinide elements in TRU waste in any brine present in the repository after closure. MgO will decrease actinide solubilities by consuming essentially all CO (sub 2) produced by microbial consumption of CPR materials (even if microbes consume all CPR materials in the TRU waste and waste containers), thereby buffering f (sub CO2) and pH within ranges favorable from the standpoint of actinide solubilities. MgO could also consume significant quantities of H (sub 2) O from brine or the gaseous phase. The strongly reducing conditions created by the processes that produce gas, and the low f (sub CO2) and mildly basic pH imposed by MgO will result in low solubilities of Th, U, Np, Pu, and Am, the actinides for which solubilities and distribution coefficients have been quantified.

WIPP opened for disposal activities in March 1999, starting the clock for the periodic recertification required every five years until the repository is closed. The first Compliance Recertification Application (CRA) was submitted to the EPA in March 2004. The CRA includes an up-to-date performance assessment (PA), which will consider new and changed information since the first certification. Performance assessment calculates probabilistic estimates of the long-term performance of the waste disposal system. The PA system consists of conceptual models, computational codes, parameter databases, and computer systems. Sandia National Laboratories maintains the PA system in support of compliance applications and for analyses to support changes to the disposal system. This paper provides an overview of PA with discussion of the WIPP regulatory framework, the PA methodology, conceptual and process models, scenario development, release mechanisms, major PA codes, treatment of uncertainty, the role of conservative assumptions in PA, and a summary of the results of the CRA PA.

However, the DOE has also included Np and other actinides in the WIPP Actinide Source Term Program (ASTP). Anoxic corrosion of Fe- and Al-base metals and microbial consumption of cellulosic, plastic, and rubber materials will create strongly reducing conditions in the WIPP after closure. Under these conditions, Pu, Am, U, Th, and Np will speciate essentially entirely as Pu(III) or Pu(IV), Am(III), U(IV) or U(VI), Th(IV), and Np(IV) or Np(V). The use of MgO as an engineered barrier will result in low f (sub CO2) and mildly basic pH. The WIPP ASTP developed thermodynamic speciation-and-solubility models for +III, +IV, and +V actinides in brines. Experimental data for Nd, Am, and Cm were used to parameterize the Pitzer activity-coefficient model for +III species; data for Th were used for the +IV model; and data for Np(V) were used for the +V model. These models include the effects of the organic ligands in TRU waste. The oxidation-state analogy was then used to extend the +III model to Pu(III), and the +IV model to Pu(IV), U(IV), and Np(IV). The solubility of U(VI) was estimated. For the recent WIPP Compliance Recertification Application, we calculated +III, +IV, and +V actinide solubilities with f (sub CO2) buffered by the brucite-hydromagnesite (Mg (sub 5) (CO (sub 3) ) (sub 4) (OH) (sub 2) 4H (sub 2) O) carbonation reaction (vectors with microbial activity) or the brucite-calcite carbonation reaction (vectors without microbial activity), and with pH buffered by the brucite dissolution reaction. Calculated +III solubilities vary from 1.69 X 10 (super -7) to 3.07 X 10 (super -7) M, depending on brine type and whether or not microbial activity occurs; those for the +IV actinides vary from 5.84 X 10 (super -9) to 2.47 X 10 (super -8) M; the +V solubilities vary from 9.72 X 10 (super -7) to 2.13 X 10 (super -5) M. The estimated +VI solubilities are 8.7 X 10 (super -6) or 8.8 X 10 (super -6) M. Acknowledgement: this research is funded by WIPP programs administered by the U.S. Department of Energy.

The principal water-bearing unit at the WIPP site is the Culebra Dolomite Member of the Rustler Formation, which lies approximately 440 m above the repository. When the DOE submitted its Compliance Certification Application to the Environmental Protection Agency in 1996, heads in the Culebra were thought to be in a steady-state condition, perturbed only by drilling and testing activities. Subsequent monitoring showed Culebra water levels to be fluctuating in unexpected ways on nongeologic time scales. DOE therefore initiated an investigation to determine the cause(s) of the water-level fluctuations and evaluate potential impacts on WIPP's regulatory compliance. Three hypotheses involving human activities were developed to explain the water-level changes: 1) potash processing effluent discharged onto a tailings pile upgradient of the WIPP site may be leaking into the Culebra through poorly plugged boreholes beneath the tailings pile or through subsidence fractures; 2) water from overlying units may be leaking into the Culebra through poorly plugged potash exploration holes; and 3) brine injected into deeper formations for secondary oil recovery or salt-water disposal may be leaking into the Culebra, either through casing failures in the injection well(s) or through nearby poorly plugged boreholes. Both field and modeling activities were initiated to address these hypotheses. New wells were installed downgradient of the potash tailings pile and in other areas where data were lacking. Bureau of Land Management and New Mexico Oil Conservation Division databases were searched to: 1) identify exploration holes and wells that may have been inadequately plugged, and 2) obtain information on injection wells, their target horizons, and injection rates. Records from the New Mexico Office of the State Engineer show how much water is pumped for potash refining. Modeling studies show that some combination of leakage from the tailings pile and leakage through boreholes in other locations is required to match the observed spatial distribution of water-level changes. None of the scenarios considered suggest any threat to WIPP's compliance with regulations.

The interactions between the functional molecules and the minerals are best represented in diatoms, sea shells, bone tissue and bacterial produced magnetic particles. These natural minerals and biominerals not only have remarkable structural ordering on multiple length scales, but also have well-controlled morphologies. High-pressure polymorph minerals (e.g., aragonite) and high-temperature polymorph minerals (e.g., wurtzite ZnS) can be precipitated with assistance of certain organic molecules at low pressure and low temperature environments. In order to simplify the mechanism of mineral growth in organic-bearing solutions, we used lipid-like surfactants and simple organic molecules with -COOH and -NH2 functional groups to study the effect of organics on mineral growth. Silica precipitates with diatom-like shapes were synthesized through self-assembly of organics and inorganic silica in surfactant-bearing solutions. The shape of precipitated silica changes as surfactant concentration, ratio of two surfactants, or trace metals (e.g., Al) changes is solutions. An organic acid with -COOH functional group can control crystal shape and even seashell-like texture of zincite. Fish-bone like nanostructured zincite can be synthesized in a solution containing an organic with -NH2 functional group. Organic molecules with -NH2 functional group result in the growth of ZnS with wurtzite structure and intergrowth of sphalerite and wurtzite domains, although sphalerite is a thermodynamically stable phase at low-temperature. This study will enhance our understanding of solution-organic-mineral interactions that are critical in mineral formation. Our results will also provide useful information about bacterial origin of minerals in terrestrial samples and open new opportunities for studying possible microbial activities in extraterrestrial samples.

In this paper, we show that the interstratification can autonomously emerge from a nonlinear mineral growth kinetics, which is described by a generalized logistic equation accounting for two countering factors: the saturation degree of solution and the strain energy between the two different structural components involved in the layer stacking. Chaotic interstratifcation occurs when the two structural components have a certain degree of dissimilarity and the solution is close to equilibrium with respect to each end-member phase. The chaos model proposed here has successfully predicted the associations of both mineral phases and layer sequences. Our work indicates that the transition from one interstratification mode to another reflects a change in chemical environment during phyllosilicate crystallization.

Existing data indicate that the contribution of nanopores to the total surface area in geologic materials can be very high, probably over 90 percents. To clarify the effect of nanopore confinement, acid-base titration and metal adsorption experiments were performed on both nanoporous alumina and alumina particles under various chemical conditions. The experiments have demonstrated that the nano-scale confinement has a significant effect, most likely via the overlap of the electric double layer, on ion sorption onto nanopore surfaces. Under the same chemical conditions, the surface charge per mass on nanoporous alumina was as much as 45 times higher than that on alumina particles. The nanopore confinement leads to a shift of ion sorption edges and enhances ion sorption on nanopore surfaces for both cations and anions. As a result, trace elements in natural systems tend to be preferentially enriched in nanopores. This effect cannot be adequately modeled by existing surface complexation models. To understand the state of water in nanopores, the experiment of water adsorption under various relative-humidity conditions were performed in combination with H magic-angle spinning nuclear magnetic resonance (MAS NMR) and Fourier transform infrared (FTIR) spectroscopic analyses. The experimental results show that water molecules in nanopores form more rigid structures than those in bulk solutions. The observed nanopore confinement effects will shed a light on our understanding many fundamental geochemical issues such as the bioavailability of contaminants and the formation of ore deposits.

In its May 1998 certification rulemaking, the U.S. Environmental Protection Agency specified MgO as the only engineered barrier in the WIPP disposal system. MgO will decrease actinide solubilities by consuming essentially all aqueous or gaseous CO (sub 2) produced by microbial consumption of cellulosic, plastic, and rubber (CPR) materials (even if microbes consume all CPR materials in the repository), thereby buffering f (sub CO2) and pH within ranges favorable from the standpoint of actinide solubilities. The DOE is emplacing significantly more MgO than required to consume all CO (sub 2) . MgO could also consume significant quantities of H (sub 2) O from brine or the gaseous phase. MgO is being emplaced in polypropylene "supersacks" on top of the stacks of waste containers. Each supersack contains 1905 + or - 23 kg of MgO. Emplacement in supersacks: (1) facilitates handling and emplacement of MgO; (2) minimizes potential worker exposure to dust; (3) minimizes the exposure of periclase, the main reactive constituent of MgO, to atmospheric CO (sub 2) and H (sub 2) O during handling and emplacement, and prior to panel closure. The supersacks contain dry, granular MgO, of which less than 0.5 % can exceed 9.5 mm in diameter. Emplacement of granular MgO instead of powder (1) results in a bulk density high enough that sufficient MgO can be emplaced without causing operational difficulties, (2) reduces the likelihood of release of dust in the event of premature rupture of a supersack, and (3) ensures that the permeability of the material is high enough to promote complete reaction with CO (sub 2) . Creep closure of WIPP disposal rooms will rupture the supersacks and disperse the MgO among and within ruptured waste containers.

Understanding such controls is fundamental to developing accurate models for design, forecasting or prediction. Here we integrate highly resolved permeability and porosity measurements, visual rock attributes and numerical modeling to explore the effects of small-scale heterogeneity on solute transport. A 30 cm by 30 cm by 2 cm slab of Massillon Sandstone was selected for the research due to the distinct cross bedding and nested scales of heterogeneity. Conservative solute transport experiments were conducted with potassium iodide to study the effects of heterogeneous permeability and porosity on solute transport. Experiments are run both perpendicular and parallel to cross-bedded features of the sandstone. Porosity and tracer distribution at sub-millimeter resolutions are obtained through X-ray adsorption imaging. Permeability heterogeneity was characterized by 8649 measurements collected with a gas permeameter using a 1.5 mm inner tip seal radius. The measured heterogeneity is used to numerically simulate experimental tracer tests. Simulations are run with MODFLOW and numerical results are compared to experimentally derived tracer distributions. Initial results yield poor comparisons between the measured and modeled tracer distributions. A thorough investigation of potential experimental errors, including boundary conditions, permeability measurements, and tracer injection distributions, suggest that the problems may result from permeability heterogeneity at scales smaller than can be resolved with the 1.5 mm tip seal. Numerical models show that boundaries between cross-stratified beds have a large impact on fluid flow, and that lower permeability layers along these boundaries may account for the fluid transport seen in the experiments. Thin sections show concentrations of hematitic cement and clays in these regions, which are oriented parallel to the direction of gas permeameter injection, possibly biasing permeability measurements.

Unfortunately, there are not yet sufficient supporting tools that integrate the myriad values involved in water policy to allow a collaborative team to see benefits and tradeoffs among various management options. This project is developing a generic resource-planning "toolbox"--a collection of process modules and constitutive relations that an analyst can "swap" in and out to model the physical and social systems important to a specific issue. For water management, the technical challenge lies in integrating disparate systems of hydrology, ecology, climate, demographics, economics, policy, and law. Therefore, the first task was to assemble a multidisciplinary research team that includes expertise in all of the above categories. After one year, this team has developed an initial framework for the "toolbox" within a system dynamics platform. System dynamics provides a mathematical framework for integrating the natural and social processes and utilizes an interactive interface for engaging the public. System dynamics is based on the concept of a spatially aggregated and temporally dynamic commodity balance. These models focus on capturing the feedback and time delays between interacting subsystems. A key value is that they can reveal complex relationships that are often non-intuitive among the physical and/or social systems. This effort has uniquely included social parameters that are crucial in water policy decisions, but difficult to integrate into a mathematical model. Using heuristic information, system dynamics allows the model to integrate typically qualitative data, such as cultural values or behavioral motivations that are not price-driven. The models allow simulations to be conducted in a matter of seconds to minutes. Through the interactive interfaces, the public or decision-makers can generate "what if" scenarios and see the implications of various combinations of actions and what is driving the outcome. This talk will cover the dynamic of working within a multidisciplinary modeling team and will demonstrate the "toolbox."

A 6.9 g L-1 slug of NaCl was applied to a 3 by 3 m area for 85 d at a flux of 2.7 cm d-1. Electrical conductivity measurements were collected weekly, using 13 12-m boreholes installed in a 15 by 15 m area. The measured bulk soil electrical conductivity (ECa) was converted to soil water electrical conductivity (ECw) using water contents from neutron probe measurements and clay contents from soil cores. The calculated mass of salt in the profile agreed well with the known mass of salt infiltrated when the appropriate immobile water content was assumed. The low water content, theta w, (<15% by volume) and low bulk soil electrical conductivity, ECa, (<100 mS m-1) measured at the test site presented more resistive conditions than previous studies of this type and were a cause of uncertainty in the results. Good agreement between calculated and known ECw resulted from the ability to measure theta w and ECa in the same locations. Sensitivity analyses showed that the calculated ECw was strongly dependent on the assumed upper limit of immobile water content, and less sensitive to soil temperature and clay content. The results of this study demonstrate that downhole EM methods can accurately characterize water and solute distributions in the vadose zone.

This clarification described the use of the gastrointestinal tract model, respiratory tract model, and transfer compartment in calculations of tritium metabolism. This information was used to derive intake retention fractions for tritium and tritium compounds including tritiated water, organically bound tritium, and tritides. In addition, dose coefficients were derived for tritide compounds including general categories described by the ICRP and some specific compounds.

Using a novel algorithm, submovements were extracted from the point-to-point movements of 41 persons recovering from stroke. Analysis of the extracted submovements showed that, over the course of therapy, patients' submovements tended to increase in peak speed and duration. The number of submovements employed to produce a given movement decreased. The time between the peaks of adjacent submovements decreased for inpatients (those less than 1 month post-stroke), but not for outpatients (those greater than 12 months post-stroke) as a group. Submovements became more overlapped for all patients, but more markedly for inpatients. The strength and consistency with which it quantified patients' recovery indicates that analysis of submovement overlap might be a useful tool for measuring learning or other changes in motor behavior in future human movement studies.

We investigate the feasibility of translating lithofacies into hydrofacies by testing the hypothesis that the permeability frequency distributions of different lithofacies are distinct. We mapped 11 lithofacies and performed more than 1800 in situ permeability measurements at an outcrop exposing poorly cemented, nonmarine, clastic sediment. The lithofacies represent both channel and interchannel deposits, are both ribbon-form and tabular, and vary in grain size from clay to sandy gravel. For each lithofacies permeability sample, we calculated variograms to define correlation lengths that were used to select spatially uncorrelated subsamples from each sample. The frequency distributions of permeability subsamples from the various lithofacies were compared using nonparametric statistical tests. The statistical tests generally support the claim that the lithofacies permeability distributions are distinct from one another.

Multiple parameters control the shapes, proportions, and spatial relationships of the objects defining the different facies in the resulting simulations. A sensitivity analysis is performed here to determine the sensitivity of several different performance measures of groundwater flow in a fluvial-basin aquifer to the parameterization of the object-based model. Unconditional realizations of the permeability field are created through an object-based model that simulates multiple facies (channel, levee, splay, and floodplain deposits) in a fluvial depositional system. A single permeability value is assigned to each facies. For each realization, Latin hypercube sampling is used to draw the input parameters from predefined distributions characterizing the uncertainty inherent in these parameters. Groundwater flow is simulated parallel to the principal channel azimuth, and the groundwater flow patterns are determined by tracking streamlines through multiple realizations of the simulated aquifer. Results on groundwater flow include points on the distributions of travel times, tortuosity of flow paths, and dispersion of the flow patterns. The values of the input parameters are compared to the results on groundwater flow using a generalized sensitivity analysis to provide a quantitative technique for the assessment of parameter sensitivity. Results of this sensitivity analysis show that a first-order characterization goal must be determination of the proportions of the high-permeability (channel) and low-permeability (floodplain) facies within the aquifer. To a lesser degree, the performance measures of groundwater flow are sensitive to the channel sinuosity, thickness, and width-to-thickness ratio. These results can be used to provide guidance towards more efficient characterization of fluvial depositional settings for groundwater studies.

Based on the latest figures from the United Nation's "World Water Development Report," more than 50 percent of the nations in the world will face water stress or water shortages by 2025, and by 2050, as much as 75 percent of the world's population could face water scarcity (United Nations, 2003). Like so much of the world, access to fresh water is an increasingly critical issue in the southwestern United States. Over the past several decades, a tremendous growth in population and industry in the Southwest has increased the demand for water and has lead to unsustainable water management practices. The consequences of these practices are groundwater mining, falling water tables with ground subsidence and associated building and utility damage, and reductions in surface and groundwater quality and availability.

XBGPR attenuation tomography is conducted in order to test the ability of using images of electromagnetic attenuation for hydrogeologic investigations. The results of four pre-infiltration attenuation inversions shows standard deviations below 0.1 Np/m, and demonstrate the consistency of the XBGPR tomography technique for making time-lapse observations. Correlation to the core records indicates that XBGPR attenuation tomograms provide high-resolution images of clay distribution in the vadose zone. Water infiltration at the ground surface was initiated in February 1999 at a constant rate of 2.7 cm/day, and continued at this rate throughout the data collection experiment. Time-lapse attenuation tomograms show that attenuation increases by approximately 0.3 Np/m during the water infiltration, and indicate a snowplow effect may be occurring where salts are dissolved by the water and concentrated at the front of the plume. Seasonal temperature changes may also cause changes in electromagnetic attenuation images, and masking the evidence of water infiltration. Thus caution must be taken when using time-lapse attenuation images to interpret the movement of a water plume during a long-term experiment as temperature changes.

We demonstrated simple and rapid techniques for determining plasma viscosity without cell separation, for measuring erythrocyte sedimentation rate, and for tracking blood coagulation throughout the entire process. Additionally, mathematical models, previously developed to characterize surface-loaded resonators, were used to extract non- Newtonian and viscoelastic material properties of blood layers during sedimentation and coagulation experiments. These studies indicate the utility of the TSM resonator for several clinical applications. Because the resonators can be miniaturized, potential exists for extending the techniques for use inside the body or blood stream (in vivo).

A laser-extinction technique was used to make quantitative measurements of path-length-averaged soot volume fraction. Flame luminosity and planar laser-induced incandescence imaging were used to visualize the sooting region of the fuel jet. Flame lift- off lengths were also measured and used in the interpretation and analysis of the soot measurements. Fuel was injected with a common-rail diesel fuel injector equipped with a single 100- mu m-diameter orifice. The fuel used was #2 diesel fuel. The matrix of experimental conditions included ambient gas temperatures from 850 to 1300 K, ambient gas densities from 7.3 to 30.0 kg/m, and injection pressures from 43 to 184 MPa. The results show that peak soot level in a fuel jet increases with increasing ambient gas temperature, with the increase scaling linearly with temperature. However, near the tip of the flame, the soot levels decrease with increasing ambient temperature, indicating significantly higher soot oxidation rates in the flame-tip region at higher temperatures. The results also show that the peak soot level in a fuel jet increases with increasing ambient gas density and decreasing injection pressure. The increase with increasing ambient density is nonlinear with respect to density. The increase with decreasing injection pressure is linear with decreasing injection velocity (or the square root of the pressure drop across the injector orifice). Overall, the trends observed in diesel fuel jet soot closely correlate with the cross- sectional average equivalence ratio at the lift-off length, with soot levels decreasing as the equivalence ratio decreases (i.e. as more air entrainment and mixing of fuel and air occur upstream of the lift-off length).

AN - 71927938; 15144837 AB - A series of hybrid organic-inorganic nanocomposite materials was synthesized by three different procedures using sodium dodecyl sulfate (DDS) and magnesium-aluminum layered double hydroxide (Mg/Al LDH with a Mg/Al molar ratio of 2 to 5). Both the pH of the exchange medium (6.5 to 10) and the Mg/Al molar ratio of the LDH affected the basal spacing, the content of DDS retained and the orientation of the DDS chains within the interlamellar space. For LDH with higher charge density (Mg/Al=2 and 3), DDS molecules likely formed a perpendicular monolayer within the LDH interlayer and the solution pH had little effect on the basal spacing, with a mean and standard deviation of 25.5+/-0.4 A. However, for LDH with lower charge density (Mg/Al=4 and 5), DDS molecules more likely formed an interpenetrating bilayer, and the basal spacing significantly increased with increasing pH, with a mean and standard deviation of 32.7+/-5.2 A. Sorption of trichloroethylene and tetrachloroethylene by DDS-LDH varied with synthesis conditions, LDH type and DDS configuration in the interlayer. DDS-Mg(3)Al-LDH had the highest affinity for both trichloroethylene and tetrachloroethylene in water, either comparable to or as much as four times higher than other clay-derived sorbents, followed by DDS-Mg(4)Al-LDH and DDS-Mg(5)Al-LDH. DDS-Mg(2)Al-LDH had the lowest sorption affinity although the highest amount of DDS. The pH of the exchange solution also affected the amount of DDS retained by the LDH as well as the sorption efficiency. Mg(3)Al-LDH has a charge equivalent area of 32.2 A(2)/charge, which allows the formation of optimal DDS configuration within its interlayer, thus resulting in the highest affinity for the chlorinated compounds. The DDS-Mg/Al-LDHs can be easily synthesized either ex situ or in situ at low temperature, indicating the feasibility of practical applications. The results obtained by controlling the synthesis procedure suggest that different arrangements of DDS molecules in the LDH interlayers can be obtained and optimized for the sorption of specific sorbates.

Four species of bacteria were studied: the Gram-negative Escherichia coli and the Gram-positive Bacillus subtilis, B. cereus, and B. megaterium. Under an applied direct current (DC) electric field all the bacterial species exhibited negative dielectrophoretic behavior. The dielectrophoretic separations were carried out in a glass microchannel containing an array of insulating posts. The insulating posts in the microchannel produced nonuniformities in the electric field applied along the channel. Mixtures of two species of bacteria were introduced into the microchannel and the electric field was applied. The bacterial species exhibited different dielectrophoretic mobilities under the influence of the nonuniform field. From these experiments a trapping order was established with E.coli trapping at the weakest applied electric field, while the Bacillus species were trapped at different characteristic threshold fields. At stronger applied electric fields, the two different species of bacteria in the microchannel were dielectrophoretically trapped into two spatially distinct bands. The results showed that iDEP has the potential to selectively concentrate and separate different species of bacteria.

In a Markov chain model of these interrelations, actions depend on the individual behaviors of particular subsystems, the time at which the subsystem is responding, and the history of occurrences leading up to the response time. Aggregation of effects leading to a result is rarely linear, so a nonlinear weighted sum called "chained soft aggregation" is proposed as an appropriate model. The method is readily combined with any available objective information in a hybrid analysis.

Rapid and inexpensive fabrication of nanoporous microdialysis membranes in microchips is achieved using a phase separation polymerization technique with a shaped UV laser beam. By controlling the phase separation process, the molecular weight cutoffs of the membranes can be engineered for different applications. Counterflow dialysis is used to demonstrate extraction of low molecular weight analytes from a sample stream, using two different molecular weight cutoff (MWCO) membranes; the first one with MWCO below 5700 for desalting protein samples, and the second one with a higher MWCO for size-based fractionation of proteins. Modeling based on a simple control volume analysis on the microdialysis system is consistent with measured concentration profiles, indicating both that membrane properties are uniform, well-defined, and reproducible and that diffusion of subcutoff analytes through the membrane is rapid.

Live and dead Escherichia coli were concentrated and selectively released by applying stepped DC voltages across a microchannel containing an array of insulating posts etched in glass. The only electrodes present were two platinum wires placed in the inlet and outlet reservoirs, producing mean electric fields of up to 200 V/mm across the insulators. The cells were labeled with Syto 9 and propidium iodide and imaged through a fluorescent microscope. Cell trapping and release were controlled by modifying the relative responses of electrokinesis and DEP by adjusting the magnitude of the applied voltage. Dead cells were observed to have significantly lower dielectrophoretic mobility than live cells, whereas the electrokinetic mobilities of live and dead cells were indistinguishable. The locations of the bands of differentially trapped cells were consistent with predictions. In addition, cells were selectively trapped and concentrated against backgrounds of 1- and 0.2- mu m carboxylate-modified polystyrene particles. This first application of iDEP for simultaneous live/dead bacteria separation and concentration illustrates its potential as a front-end method for bacterial analysis.

AN - 85380934; pmid-15058325 AB - In this paper the response of the external auditory system to acoustical waves of varying frequencies and angles of incidence is computed using a boundary element method. The resonance patterns of both the ear canal and the concha are computed and compared with experimental data. Specialized numerical algorithms are developed that allow for the efficient computation of the eardrum pressures. In contrast to previous results in the literature that consider only the "blocked meatus" configuration, in this work the simulations are conducted on a boundary element mesh that includes both the external head/ear geometry, as well as the ear canal and eardrum. The simulation technology developed in this work is intended to demonstrate the utility of numerical analysis in studying physical phenomena related to the external auditory system. Later work could extend this towards simulating in situ hearing aids, and possibly using the simulations as a tool for optimizing hearing aid technologies for particular individuals.

Inverse-quantitative structure-activity relationship of ICAM-1 inhibitory peptides. AN - 71984759; 15177078 AB - We present a methodology for solving the inverse-quantitative structure-activity relationship (QSAR) problem using the molecular descriptor called signature. This methodology is detailed in four parts. First, we create a QSAR equation that correlates the occurrence of a signature to the activity values using a stepwise multilinear regression technique. Second, we construct constraint equations, specifically the graphicality and consistency equations, which facilitate the reconstruction of the solution compounds directly from the signatures. Third, we solve the set of constraint equations, which are both linear and Diophantine in nature. Last, we reconstruct and enumerate the solution molecules and calculate their activity values from the QSAR equation. We apply this inverse-QSAR method to a small set of LFA-1/ICAM-1 peptide inhibitors to assist in the search and design of more-potent inhibitory compounds. Many novel inhibitors were predicted, a number of which are predicted to be more potent than the strongest inhibitor in the training set. Two of the more potent inhibitors were synthesized and tested in-vivo, confirming them to be the strongest inhibiting peptides to date. Some of these compounds can be recycled to train a new QSAR and develop a more focused library of lead compounds.

Along with the formation stresses, pressure, and properties, the analysis predicts where microseisms should occur in relation to the fracture and makes possible accurate interpretation of the significance of the microseismic events. The most important factor controlling the seismically active zone is the coupling of the fracturing pressure into the formation. Thus, liquid-saturated reservoirs experience much more widespread activity than do gas reservoirs. The analysis also shows that the fracture tip induces large shear stresses that result in a local zone of instability. Such a zone is the primary reason that microseisms accurately map out the length and height of the fracture, because considerable microseismic activity occurs around the tip as it propagates.

These regions include gouge-filled fractures, recrystallized fracture- filling material and hydrothermally altered matrix. With the X-ray absorption imaging technique, porosity, relative concentration, and relative mass of an iodine tracer were imaged in two dimensions with a sub-millimeter pixel size. Because portions of the samples analyzed have relatively low porosity values, imaging errors can potentially impact the results. For this reason, efforts were made to better understand and quantify this error. Based on the X-ray data, pore diffusion coefficients (D sub(p)) for the different regions were estimated assuming a single diffusion rate and a lognormal multirate distribution of D sub(p). Results show D sub(p) for the gouge-filled fractures are over an order of magnitude greater than those of the recrystallized fracture-filling material, which in turn is approximately two times greater than those for the altered matrix. The recrystallized fracture-filling material was found to exhibit the greatest degree of variability. The results of these experiments also provide evidence that diffusion from advective zones in fractures through the gouge-filled fractures and recrystallized fracture-filling material could increase the pore space available for matrix diffusion. This evidence is important for understanding the performance of potential nuclear waste repositories in crystalline rocks as diffusion is thought to be an important retardation mechanism for radionuclides.

The present work is an experimental study of 36 degree YX cut LiTaO sub(3) based Love-wave devices for detection of pathogenic spores in aqueous conditions. Given that the detection limit (D sub(l)) of Love-wave-based sensors is a strong function of the overlying waveguide, two waveguide materials have been investigated, which are polyimide and polystyrene. To determine the mass sensitivity of Love-wave sensor, bovine serum albumin (BSA) protein was injected into the Love-wave test cell while recording the magnitude and phase shift across each sensor. Polyimide had the lowest mass detection limit with an estimated value of 1.0-2.0 ng/cm, as compared to polystyrene where D sub(l)=2.0 ng/cm super(2). Suitable chemistries were used to orient antibodies on the Love-wave sensor using protein G. The thickness of each biofilm was measured using ellipsometry from which the surface concentrations were calculated. The monoclonal antibody BD8 with a high degree of selectivity for anthrax spores was used to capture the non-pathogenic simulant B. thuringiensis B8 spores. Bacillus subtilis spores were used as a negative control to determine whether significant non-specific binding would occur. Spore aliquots were prepared using an optical counting method, which permitted removal of background particles for consistent sample preparation. This work demonstrates that Love-wave biosensors are promising for low-level detection for whole-cell biological pathogens.

Here we consider the simulation of such structures with a Modified form of Invasion Percolation (MIP). Results show that slender pathways form in fracture networks for a wide range of expected conditions, can be maintained when subsequent matrix imbibition is imposed, and may arise even in the context of primarily matrix flow due to the action of fractures as barriers to inter-matrix block transport.

AN - 71699451; 14995794 AB - The magnetocatalytic (or Hedvall) effect refers to a change in the rate of a chemical reaction on a magnetic surface at the Curie point T(C). For Ni catalysts, experiments suggest the effect is related to a sudden increase in segregated surface C, a strong catalytic poison, at temperatures below T(C). However, the connection between magnetism and surface segregation is not understood. Using density functional theory and spin-dynamics simulations, we show that the solubility of C in Ni is significantly reduced in the ferromagnetic state, because C suppresses Ni magnetism and thereby increases the heat of solution. This explains the observed increase in C segregation and the reduced catalytic activity below T(C).

AN - 67278354; 15803696 AB - We study nanoporous carbon (NPC) as an adsorbent coating on surface acoustic wave (SAW) chemical microsensors for a wide range of analyte gases. By use of pulsed-laser deposition in a controlled inert gas ambient, NPC grows at room temperature with negligible residual stress and, hence, can coat most surfaces to any desired thickness. Acetone adsorption isotherms for NPC-coated SAW devices with mass density ranging from 0.18 to 1.08 g/cm3 indicate that the device frequency response relates to NPC density. Data analysis suggests the possibility of detecting acetone below parts-per-billion concentrations. We find NPC to be highly sensitive to a variety of other volatile organic and toxic industrial compounds. Transmission electron microscopy reveals that lower-density NPC has both larger and greater numbers of nanopores than higher-density NPC and that decreasing NPC density also increases the interplanar spacing between graphene sheet fragments within the ultrathin carbon wall structures. These physical differences effectively increase the available surface area for analyte gas adsorption with decreasing NPC density, with only the structural integrity of the internal NPC wall structures a limiting factor in determining the lowest useful density NPC coating.

In order of sequential development, these conjugate pairs are oriented to form each of the three principal conjugate attitudes: (1) upright X's, (2) plan-view X's, and (3) recumbent X's. The symmetry axes of the three different X-geometries at this location are parallel, suggesting that the three systems are genetically related. A relatively simple stress history, with the horizontal stresses striking northeast and southeast and varying in magnitude but not in orientation, plausibly explains this suite of sequentially developed conjugate structures. In this model, the upright X's formed with dip-slip, normal offset under the initial conditions where the overburden was the maximum stress and the northeast-striking horizontal stress was the intermediate stress. Plan-view X's with strike-slip offset formed next, as the northeast-striking stress increased (due to northeastward Laramide translation of the Colorado Plateau and interaction with the local basement-cored Nacimiento Uplift) to become the maximum stress, leaving the overburden stress as the intermediate stress although unchanged in magnitude. As the northeast-directed horizontal compressive stress continued to increase, it eventually created a condition where the horizontal stresses equaled or exceeded the overburden stress, resulting in small-scale thrusting along the recumbent X's. The proposed mechanical model shows that shear stress levels dropped temporarily after the formation of the upright X's, providing a hiatus in deformation and making the deformation at the next stage distinct, without overlap. The three systems of intersecting conjugate deformation bands that resulted have severely compartmentalized potential reservoirs in this unit, and illustrate why similar high-porosity, deformation-banded units can have low hydrocarbon production rates despite otherwise good reservoir potential.

A constant and uniform supply of chemically equilibrated water was introduced to the upper surface of three artificial fractures in a surrogate fracture network consisting of a thin wall of uncemented limestone blocks. Water was collected from the lower boundary via fiberglass wicks placed at the bottom of each artificial fracture. Eight experiments were conducted to evaluate the repeatability of flow under nearly identical conditions and to characterize general patterns in flow behavior. Collected data revealed that flow generally converged to a single fracture in the bottom row of blocks. Periods of pathway switching were observed to be more common than periods with steady, constant flow pathways. We noted the importance of fracture intersections for integrating uniform flow and discharging a "fluid cascade," where water advances rapidly to the next capillary barrier creating a stop and start advance of water through the network. Under very similar initial moisture and boundary conditions, flow in the system was less repeatable than expected. The results of this simple experiment suggest that the interaction of multiple fracture intersections in a network creates flow behavior not generally recognized in popular conceptual and numerical models, (i.e., convergence of flow, pathway switching, and fluid cascades).

Data on discharge, specific conductivity (SC), total dissolved solids (TDS), pH, Ca super(2+), Na super(+), Mg super(2+), K super(+), HCO sub(3) super(-), SO sub(4) super(2-), Cl super(-), F super(-), and SiO sub(2) came from six USGS stations ranging from the Colorado-New Mexico border to below Albuquerque, New Mexico. Linear regression, Kendall's S, and Seasonal Kendall's S' were used to detect trends, and ANOVA was used to analyze spatial differences between stations. Statistically significant increasing trends occurred in SC, TDS, Ca super(2+), Na super(+), Mg super(2+), K super(+), Cl super(-), and F super(-) in the uppermost reaches, and significant decreasing trends of SC, TDS, Ca super(2+), Mg super(2+), K super(+), HCO sub(3) super(-), and SO sub(4) super(2-) occurred at the lower stations around Albuquerque. Both fluoride concentrations and pH values increased at and below Albuquerque over the study period. Discharge data show an increasing trend across all stations. Spatially, data for dissolved substances show generally linear upstream to downstream increases in concentrations in the upper four stations, with several notable nonlinear increases at and below Albuquerque (SC, TDS, Na super(+), Cl super(-)). Significant increases in pH appear at and below Albuquerque, relative to upstream stations, probably due to improved sewage treatment.

ER - TY - JOUR T1 - Expert elicitation approach for performing ATHEANA quantification AN - 19190361; 5793892 AB - An expert elicitation approach has been developed to estimate probabilities for unsafe human actions (UAs) based on error-forcing contexts (EFCs) identified through the ATHEANA (A Technique for Human Event Analysis) search process. The expert elicitation approach integrates the knowledge of informed analysts to quantify UAs and treat uncertainty ('quantification-including-uncertainty'). The analysis focuses on (a) the probabilistic risk assessment (PRA) sequence EFCs for which the UAs are being assessed, (b) the knowledge and experience of analysts (who should include trainers, operations staff, and PRA/human reliability analysis experts), and (c) facilitated translation of information into probabilities useful for PRA purposes. Rather than simply asking the analysts their opinion about failure probabilities, the approach emphasizes asking the analysts what experience and information they have that is relevant to the probability of failure. The facilitator then leads the group in combining the different kinds of information into a consensus probability distribution. This paper describes the expert elicitation process, presents its technical basis, and discusses the controls that are exercised to use it appropriately. The paper also points out the strengths and weaknesses of the approach and how it can be improved.

The theory of flow dimensions introduced by Barker in 1988 (Water Resour. Res. 24(10), 1988, 1796) provided a method of analyzing pumping (constant-rate) tests in non-radial systems, and this approach was later extended to constant-pressure tests. However, little use seems to be made of the flow-dimension approach to well-test analysis, perhaps because no easily applied method has been presented for determining, at the initial stage of an analysis, if such an approach would be productive. Depending on the distribution of heterogeneities within an aquifer, flow to a well may have almost any dimension (not limited to linear, radial, or spherical), or no constant dimension at all. Any well-test analytical solution requires that hydraulic properties be stable on some scale before those properties can be uniquely quantified. For each type of hydraulic test (constant-rate, constant-pressure, or slug/pulse), we suggest that a diagnostic plot of the scaled first or second derivative of the pressure or flow-rate response be created to determine, first, if a stable flow dimension was reached during the test and, second, what the value of that flow dimension is. If a stable flow dimension was reached, the scaled derivative will exhibit a constant value (scaled to be equal to the flow dimension). If the scaled derivative does not stabilize at a constant value, then no flow dimension can be specified and no unique hydraulic properties can be inferred analytically from the test. In all cases, the scale of testing must be appropriate to the scale of underlying interest.

Staggered-in-time loose coupling of flow and deformation via a high-level numerical interface that repeatedly calls first flow and then mechanics allows us to leverage the decades of work put into individual flow and mechanics simulators while still capturing realistic coupled physics. These two processes are often naturally modeled using different time stepping schemes and different spatial grids--flow should only model the reservoir, whereas mechanics requires a grid that extends to the earth's surface for overburden loading and may extend further than the reservoir in the lateral directions. Although spatial and temporal variability between flow and mechanics can be difficult to accommodate with full coupling, it is easily handled via loose coupling. We calculate the total stress by adding pore pressures to the effective rock stress. In turn, changes in volume strain induce updates to porosity and permeability and, hence, dynamically alter the flow solution during simulation. Incorporating the resulting time-dependent pressures, saturations, and porosities (from coupled flow and mechanics) into Gassmann's equations results in seismic wave velocities and densities that can differ markedly from those calculated from flow alone. In a synthetic numerical experiment based on Belridge field, California, incorporation of coupled flow and mechanical deformation into time-lapse calculations produces compressional wave velocities that differ markedly from those produced by flow alone. In fact, it is the closing of the pores themselves (reduction in permeability) in this example which has the greatest impact on fluid pressures and saturations and, hence, elastic wave parameters such as velocity.

Understanding the relative importance of these factors potentially contributes to the optimization of production development. Average daily gas and water production from 284 CBM wells in four El Paso Production development pods in the Raton Basin were analyzed. Stepwise linear regression was used to estimate the relative importance of independent variables, including the first and second derivatives of upper surface of the Trinidad Sandstone, total coal thickness, groundwater total dissolved solids, and duration of production, to the gas and water production. Variogram analysis was used to assess the spatial continuity in production. The correlation analysis using stepwise linear regression indicates that the total coal thickness in the Vermejo and Raton Formations accounts for about 14% of the variability in average daily gas production. The slope of the Trinidad Sandstone parallel to maximum principal horizontal stress (N 5 E) accounts for about 5% of the variability in average daily gas production. Significantly better correlation exists between the independent variables and the ratio of gas to water production, with 44% of the variability in the gas/water ratio accounted for by the slopes of the Trinidad Sandstone parallel and perpendicular to maximum principal horizontal stress. Geostatistical analysis with variography indicates that the spatial correlation in gas and water production among wells extends about 3 to 6 kilometers.

The patterns and distributions of fractures are related to mechanical stratigraphy caused by different lithologies, diagenesis, and compaction. Thus the varied stratigraphic units exhibit unique fracture patterns. Both extension and conjugate shear fractures occur within fluvial sandstones of the Raton Formation whereas extension fractures dominate the laterally extensive Trinidad Sandstone. Extension fractures are most common within the Niobrara Limestone although conjugate shear fractures also occur locally. Shear fractures dominate the silicic Dakota Sandstone. Regional fractures in Cretaceous and Tertiary strata in the basin are related to Laramide-age eastward thrusting of the Sangre de Cristo Mountains at the western margin of the basin. This relationship is indicated by extension fracture orientations that strike approximately east-west, normal to the thrust front, and proven by the related conjugate shear fractures where the bisector to the acute angle is also normal to the thrust front. These indicate that the maximum compressive stress was horizontal and oriented east-west at the time of fracturing. Such fractures and east-west face cleats in coals occur as far east as the margin of the basin, 75 miles from the thrust front. However, local structures within the basin, including anticlines and normal and thrust faults, created local fracture patterns markedly different from the surrounding east-west regional fracture pattern. Preliminary well interference data support a north-south oriented permeability trend in local areas.

New York has salt in the Silurian Salina Group, which in the south-central portion of the state is thick enough to make caverns that meet industry standards. Currently within the state there are two operational salt-cavern storage facilities and several others in various stages of completion. The greatest obstacle to completion of many of these salt caverns is disposal of the brine created during cavern devolvement. The purpose of this study is to systematically analyze potential formations for their ability to accept brine within the area where the salt is thick enough and deep enough for cavern development. We are limiting our analysis of potential brine disposal reservoirs to sandstones and carbonates (excluding shales) that have acceptable reservoir characteristics. We are now conducting a more detailed reservoir characterization on the potential targets. Our research includes porosity and permeability studies, sequence stratigraphy, mechanical stratigraphy (fracture distribution) and more. Final deliverables will include detailed analysis of usable salt distribution and potential brine reservoirs with maps, cross sections, core analysis and more. At this point in the study, the most promising prospects include the Ordovician Queenston Formation and Trenton/Black River Groups and the Cambro-Ordovician Beekmantown Group. Using New York as a representative model, we will establish a system model to be used in other regions where brine disposal is a barrier. This talk will present the current results of our efforts towards this research.

The compaction occurs as a localization process, analogous to shear localization, but results in a thickening, tabular zone of compaction as opposed to culminating in a shear fracture. We report the results of a suite of triaxial compression experiments done over a confining pressure range of 40 to 60 MPa on Castlegate Sandstone, measuring simultaneously, stress, strain, acoustic emission locations, and permeability. A major result is that compaction localization produces up to a two-order-of-magnitude decrease in permeability. Correlation of local strain measurements and acoustic emission locations made on the same specimen shows that the compaction process proceeds as a propagating front approximately 20 mm thick. A model of the compaction process was developed that incorporates the moving boundary between compacted, low-permeability regions and un-compacted, higher-permeability regions, and compaction-induced fluid injection at the boundaries. Because of the inhomogeneous nature of compaction produced by compaction localization, and its temporal evolution, a number of phenomena related to fluid flow are predicted by the model: locally increased pore pressures and spatial changes in the effective permeability. Experimental results show the evolution of effective permeability to be linear with respect to the distance the compaction fronts propagate as predicted by the model. Implications of the results for future experimentation and for reservoirs are, briefly, that the interaction between compaction-induced fluid pressure and compaction localization should lead to a phenomenon analogous to dilatancy hardening, impeding the propagation of compaction bands.

When the effects of the harder substrate on the response of the layers to indentation were accounted for, the amorphous phase was found to have a Young's modulus of 136 plus or minus 9 GPa and a hardness of 10.9 plus or minus 0.9 GPa, which were 19% and 10% lower than the corresponding values for crystalline Si. The hardness agrees well with the pressure known to induce a phase transition in amorphous Si to the denser beta -Sn-type structure of Si. This transition controls the yielding of amorphous Si under compressive stress during indentation, just as it does in crystalline Si. After annealing 1 h at 500 degree C to relax the amorphous structure, the corresponding values increase slightly to 146 plus or minus 9 GPa and 11.6 plus or minus 1.0 GPa. Because hardness and elastic modulus are only moderately reduced with respect to crystalline Si, amorphous Si may be a useful alternative material for components in Si-based microelectromechanical systems if other improved properties are needed, such as increased fracture toughness.

The software platform contains multiple modules that can be used to simulate relevant features, events, and processes that include water flux through the cover, source-term release, vadose-zone transport, saturated- zone transport, gas transport, and exposure pathways. The component models are integrated into a probabilistic total-system performance-assessment model within a drag-and-drop software platform. Uncertainty and sensitivity analyses can be conducted that yield the following primary benefits: (1) quantification of uncertainty in the simulated performance metrics; (2) identification of parameters most important to performance; and (3) comparison of alternative designs to optimize cost and performance. A case study has been performed using the Monticello Mill Tailings Site in Utah to illustrate the important features and benefits of the modeling approach and software.

In-situ analysis is imperative in understanding the erosion and transport of these sediments. Recent research efforts have developed a flume with unidirectional flow that can measure in-situ sediment erosion with depth (SEDflume). However, the flow regime for the SEDflume has limited applicability to wave-dominated environments. Therefore, a unique device, called the SEAWOLF flume, was developed and used by Sandia National Laboratories to simulate high-shear stress erosion processes experienced in coastal waters where wave forcing dominates the system. The SEAWOLF is capable of testing in-situ or laboratory prepared cores. Erosion rates of cohesive and non-cohesive sediments prepared in the laboratory were determined in oscillatory and combined oscillatory and linear flow regimes. Results of these tests were compared to results from the unidirectional SEDflume. Although maximum shear stresses for oscillatory flows were as high as 7 Pa for the tests, the associated erosion rate for specific sediment over the entire wave cycle were comparable to much lower shear stresses found for constant, linear flows. For example, sediment exposed to a maximum of 7 Pa over a 15 s period resulted in erosion rates similar to results for a constant linear shear stress of 3.4 Pa. Analysis of results for all sediments tested led to a determination of values for an effective shear stress that relates wave-induced erosion to linear flow induced erosion.

Experiments are being performed to quantify the aerosolised materials plus volatilised fission products generated from actual spent fuel and surrogate material test rods, due to impact by a high-energy-density device. The programme participants in the United States plus Germany, France and the United Kingdom, part of the international Working Group for Sabotage Concerns of Transport and Storage Casks (WGSTSC) have strongly supported and coordinated this research programme. Sandia National Laboratories has the lead role for conducting this research programme; test programme support is provided by both the US Department of Energy and the US Nuclear Regulatory Commission. The authors provide a summary of the overall, multiphase test design and a description of all explosive containment and aerosol collection test components used. They focus on the recently initiated tests on 'surrogate' spent fuel, unirradiated depleted uranium oxide and forthcoming actual spent fuel tests, and briefly summarise similar results from completed surrogate tests that used non-radioactive, sintered cerium oxide ceramic pellets in test rods.

The repository site is located in thick, partially saturated fractured tuff that will be heated to above-boiling temperatures as a result of heat generation from the decay of nuclear waste. Since water infiltrating down towards the repository will be subject to vigorous boiling for a significant time period, the superheated zone (i.e. rock temperature above the boiling point of water) may form an effective vaporization barrier that reduces the possibility of water arrival at emplacement drifts. In this paper, we analyze the behavior of episodic preferential flow events that penetrate down into the hot fractured rock zone, and evaluate the impact of such flow behavior on the effectiveness of the vaporization barrier. The characteristic features of episodic preferential flow are estimated from laboratory experiments and described by appropriate probability distributions. A semi-analytical solution is utilized to determine the complex flow processes in the hot rock environment. The solution is applied at several discrete times after emplacement, in order to cover the time period of strongly elevated temperatures at Yucca Mountain.

These gaps show as gaps in information, gaps in implementation, gaps in technological and management tools, and gaps in understanding of fundamental processes. The secondary objective is to propose a management strategy to close the identified gaps. Several methods are used to meet these objectives: surveys distributed to selected staff in each regional council; the review of various written reports; the analysis of land-use databases; and private consultation within each regional council. Results show that groundwater management in New Zealand is generally reactionary with the main gaps being in strategic planning and national guidelines. Most gaps appear to be predominantly information and implementation issues. In some cases there are gaps in the understanding of fundamental processes within an aquifer system, including the long-term effects of land-use on groundwater quality. An adaptive management approach is suggested as a means of closing these gaps.

Contaminants travel by advection and diffusion and may sorb onto fracture walls and colloids, as well as diffuse into and sorb onto the surrounding porous rock matrix. Colloids also travel by advection and diffusion and may sorb onto fracture walls, but do not penetrate the rock matrix. A probabilistic form of the Boltzmann law is used to describe attachment of colloids and contaminants onto fracture walls. For colloids that have diffused into the matrix, a linear distribution coefficient governs their sorption; an irreversible kinetic isotherm is employed to describe contaminant sorption onto colloids. Ensemble averaged breakthrough curves of many fracture realizations are used to compare arrival times of colloid and contaminant plumes at the fracture outlet. Results show that the presence of colloids enhances contaminant transport (decreased residence times) while matrix diffusion and sorption onto fracture walls retard the transport of contaminants.

Issues such as water turbidity, associated contaminants, reservoir sedimentation, undesirable erosion and scour, and aquatic habitat are all linked to sediment properties and behaviors. In situ analysis is necessary to develop an understanding of the erosion and transport of sediments. Sandia National Laboratories has recently patented the Adjustable Shear Stress Erosion and Transport (ASSET) Flume that quantifies in situ erosion of a sediment core with depth while affording simultaneous examination of transport modes (bedload versus suspended load) of the eroded material. Core erosion rates and ratios of bedload to suspended load transport of quartz sediments were studied with the ASSET Flume. The erosion and transport of a fine-grained natural cohesive sediment were also observed. Experiments using quartz sands revealed that the ratio of suspended load to bedload sediment transport is a function of grain diameter and shear stress at the sediment surface. Data collected from the ASSET Flume were used to formulate a novel empirical relation for predicting the ratio of bedload to suspended load as a function of shear stress and grain diameter for noncohesive sediments.

Because radionuclides released from the proposed repository at Yucca Mountain must travel through the saturated fractured tuff and the saturated alluvium before reaching the compliance boundary, it is important to characterize the hydrogeologic properties of the downgradient media. Since the completion of the C-Wells multi-borehole complex in 1983, several single and cross-hole tracer and pumping tests have been conducted to gain a better understanding of the hydrogeology of the region. A number of published studies have assigned transmissivities, storativities, and anisotropy ratios to the saturated zone in this area.

The German Asse repository will also employ an Mg(OH) (sub 2) (brucite)-based engineered barrier. The chemical function of the engineered barrier is to consume CO (sub 2) that may be generated by the microbial degradation of organic materials in waste packages. Experimental results at SNL indicate that MgO is first hydrated as brucite, and then brucite is carbonated as hydromagnesite (5424) (Mg (sub 5) (CO (sub 3) ) (sub 4) (OH) (sub 2) .4H (sub 2) O). As MgO is in excess relative to CO (sub 2) that may be produced, the brucite-hydromagnesite (5424) assemblage would buffer f (sub CO2) in the repository. Consequently, the thermodynamic properties of this assemblage is of great significance to the performance assessment (PA) as actinide solubility is strongly affected by f (sub CO2) . In turn, PA is important to the demonstration of the long-term safety of nuclear waste repositories, as assessed by the use of probabilistic performance calculations. There is a substantial discrepancy for Delta (sub f) G (super o) (sub brucite) in recent publications, ranging from -830.4 (Harvie et al., 1984; Geochim. Cosmochim. Acta, 723-751), through -831.9 (Brown et al., 1996; J. Chem. Soc., Dalton Trans., 3071-3075), through -833.5 (Robie and Hemingway, 1995; USGS Bull., 2131), and to -835.9 kJ mol (super -1) (Konigsberger et al., 1999; Geochim. Cosmochim. Acta, 3105-3119). Using the Delta (sub f) G (super o) (sub hydromagnesite (5424)) from Konigsberger et al., the predicted log f (sub CO2) for this assemblage would range from -5.96 (Delta (sub f) G (super o) (sub brucite) from Harvie et al.) to -4.84 (Delta (sub f) G (super o) (sub brucite) from Konigsberger et al.). Therefore, it is desirable to better constrain the Delta (sub f) G (super o) (sub brucite) . For this reason, a series of solubility experiments involving brucite in NaCl solutions ranging from 0.01 M to 4.0 M have being conducted at SNL. The derived Delta (sub f) G (super o) (sub brucite) from this study by extrapolation to infinite dilution via Pitzer formalism is -830.8 kJ mol (super -1) , which is in excellent agreement with recommended values of Harvie et al. and Brown et al.

Earthquake-induced water-level drops on and north of the resurgent dome may represent diffusion of localized fluid pressure drops induced abruptly by seismic waves. We evaluate this hypothesis using recent data from the Long Valley Exploration Well (LVEW), a 3 km deep borehole penetrating the center of the resurgent dome. The uncased interval of the LVEW penetrates relatively impermeable metapelite, and fluid communication is primarily through a conductive fracture 2.6 km below the surface. It has proven useful to collect data using pressure-temperature logging tools built to operate for extended periods at the depth of the fracture zone (temperature 102 degrees C, pressure 22.3 MPa). Data from a pumping test in September, 2001, are consistent with a high-conductance planar fracture 10-100 m long in country rock with hydraulic diffusivity of 1-10 m (super 2) /s. Tidal amplitudes at the fracture zone depth are 1.93 kPa peak-to-peak, and the ratio of pressure change to strain based on the M2 earth tide constituent is 30.3 kPa/microstrain. Both the Hector Mine, California (Oct. 16, 1999, M7.1) and Denali Fault, Alaska (Nov. 4, 2002, M7. 9) earthquakes produced steplike pressure drops in the LVEW which reached their minimum values (1.24 kPa and 1.17 kPa, respectively) within 3 hours. In contrast, water level drops induced by the same two earthquakes at the shallower LKT well, 4 km NW of the center of the dome, required 10 to 15 days to reach their minima. The Denali Fault earthquake response at the LVEW was not only faster than at LKT, but also about twice as large, consistent with fluid pressure changes occurring abruptly with the passage of seismic waves at a location closer to the LVEW than to LKT. The pressure drops caused by the Hector Mine earthquake are less consistent with this conceptual model, because the fluid pressure dropped slightly more in LKT than in the LVEW. Continued fluid-pressure monitoring should yield more information about the time-space distribution of earthquake-induced fluid-pressure changes at Long Valley.

Two important questions being considered by the Yucca Mountain Project at the lab scale are: "Can we predict the effects of scale on the mechanical properties?" and "We know that the tuff mechanical properties are highly dependent on porosity, but does the distribution of the porosity significantly alter the effect?" Relative to the first question, two empirical models show a consistent pattern of behavior in the welded tuffs. Samples from the middle non-lithophysal zone of the Topopah Spring, with volumes varying over an order of magnitude, were tested in the mid-1980's. Recently, a second series of tests have been conducted on another section of the same unit. When the data are plotted as ultimate strength versus sample volume in log-log space, two groupings are apparent. The best-fit curves to the data are parallel, but offset. The offset is believed to be the result of different porosities in the samples tested. It has been shown that total porosity appears to be the first-order factor in determining the strength of the tuffs; however, the distribution of porosity likely has a secondary effect on strength. The trends in the ultimate strength versus (total) porosity data indicate that, although there is a large scatter in the data, there is a clear correlation between strength and porosity. As a result, knowing the total porosity provides an indirect measure of the intact strength, within uncertainty bounds. One of the key elements in the design of the potential repository at Yucca Mountain, Nevada, is the stability of the possible emplacement drifts. Mechanical property data collected in the lab are vital to having confidence in the near- and far-field modeling of the facility. Two key aspects of these studies involve the sample size and the size of contained pores and how these factors affect the mechanical properties. The results from recent studies have shed light on these issues and will be presented here.

The primary objective of this project was to develop, test and validate a vulnerability assessment methodology (VAM) for determining the security of chemical facilities against terrorist or criminal attacks (VAM-CF). The project also included a report to the Department of Justice for Congress that in addition to describing the VAM-CF also addressed general observations related to security practices, threats and risks at chemical facilities and chemical transport. In the development of the VAM-CF Sandia leveraged the experience gained from the use and development of VAs in other areas and the input from the chemical industry and Federal agencies. The VAM-CF is a systematic, risk-based approach where risk is a function of the severity of consequences of an undesired event, the attack potential, and the likelihood of adversary success in causing the undesired event. For the purpose of the VAM-CF analyses Risk is a function of S, L sub(A), and L sub(AS), where S is the severity of consequence of an event, L sub(A) is the attack potential and L sub(AS) likelihood of adversary success in causing a catastrophic event. The VAM-CF consists of 13 basic steps. It involves an initial screening step, which helps to identify and prioritize facilities for further analysis. This step is similar to the prioritization approach developed by the American Chemistry Council (ACC). Other steps help to determine the components of the risk equation and ultimately the risk. The VAM-CF process involves identifying the hazardous chemicals and processes at a chemical facility. It helps chemical facilities to focus their attention on the most critical areas. The VAM-CF is not a quantitative analysis but, rather, compares relative security risks. If the risks are deemed too high, recommendations are developed for measures to reduce the risk. This paper will briefly discuss the CFVA project and VAM-CF process.

Small numbers of calibration targets and correlation between model parameters in these inverse solutions can lead to a relatively large region in parameter space that will produce a near optimal calibration of the T field to measured heads. Most applications of these inverse techniques have not considered the effects of non- unique calibration on subsequent predictions made with the T fields. Use of these T fields in predictive contaminant transport modeling must take into account the non-uniqueness of the T field calibration. A recently developed 'predictive estimation' technique is presented and employed to create T fields that are conditioned to observed heads and measured T values while maximizing the conservatism of the associated predicted advective travel time. Predictive estimation employs confidence and prediction intervals calculated simultaneously on the flow and transport models, respectively. In an example problem, the distribution of advective transport results created with the predictive estimation technique is compared to the distribution of results created under traditional T field optimization where model non-uniqueness is not considered. The predictive estimation technique produces results with significantly shorter travel times relative to traditional techniques while maintaining near optimal calibration. Additionally, predictive estimation produces more accurate estimates of the fastest travel times.

AN - 75753991; 14535318 AB - The release rates and transformation processes that influence the mobility, biological uptake, and transfer of radionuclides are essential to the assessment of the health effects in the food chain and ecosystem. This study examined concentrations of 222Th in both soil and vegetation at a closed military training site, Kirtland Air Force Base (KAFB), New Mexico. Brazilian sludge was intentionally introduced into the topsoil in the early 1960s to simulate nuclear weapon accidents. Soil (60) and vegetation (120) samples were collected from 1996 to 2000 and analyzed for radionuclides and progeny. High-resolution gamma-ray spectroscopy was used to determine radionuclide activities. The results indicate that the thorium progeny were the predominant contaminant in soil and vegetation. Concentration ratios (CRs) were calculated based on actinium levels.

AN - 73670674; 13678370 AB - The intrusion of moisture into landfills can pose a health hazard because of the possibility that the moisture will carry harmful substances into the groundwater. Early detection of moisture anywhere within these landfills is essential if corrective action is to be taken well before an occurrence of this kind. This paper presents the results of a field-scale simulation test of the use of fiber optics to detect the presence of moisture within landfill covers, using a detection method based on the thermal response of soils as a function of their moisture content. By sending electrical current through an embedded stainless-steel tube, soils of varying moisture content were heated and time-dependent temperature measurements were obtained with a fiber-optic distributed temperature sensor system. The optical fiber itself lay within the tube, but its temperature was a function of how rapidly heat was conducted into the surrounding medium. The results of this experiment, which are in agreement with those obtained using more traditional "point" sampling and laboratory analysis, are presented along with the strengths and limitations of the thermal-response method of detecting moisture.

AN - 73571935; 12805647 AB - Repeated exposures to bioactivated cytotoxicants such as naphthalene (NA) render the target population, Clara cells, resistant to further injury through a glutathione-dependent mechanism. The current studies were designed to test the hypothesis that the mechanism for tolerance is localized in Clara cells. We used three approaches to test this hypothesis. First, using airway explants from tolerant mice maintained in culture, we sought to determine if the mechanism of Clara cell tolerance was airway-specific. Second, using inhalation as the route of exposure, we sought to determine if Clara cells at all airways levels become tolerant to repeated inhalation exposures of NA. Third, by measuring gamma-glutamylcysteine synthetase (gamma-GCS) activity and expression we determined if tolerance to inhaled NA resulted from shifts in phase-II metabolism. Our results indicate that Clara cells in explants from tolerant mice remained tolerant to NA injury in culture. When mice were exposed to repeated inhalation exposures of NA (15 ppm), we found that Clara cells at all airway levels became tolerant. Expression and activity analysis revealed that gamma-GCS, the rate-limiting enzyme in glutathione synthesis, is induced in tolerant Clara cells. Buthionine sulfoximine, a gamma-GCS inhibitor, was able to eliminate the resistance of these tolerant cells. We conclude: (1) the mechanism of NA tolerance in Clara cells is airway specific, (2) the specific mechanism allows Clara cells to become tolerant to NA vapor at levels relevant to human exposure, and (3) the mechanism of tolerance to inhaled NA is highly dependent on induction of the catalytic enzyme, gamma-GCS.

Selective catalytic reduction of nitric oxide by ammonia over sol-gel derived CuO/ gamma -Al sub(2)O sub(3) sorbents/catalysts with different degrees of sulfation was studied in a fixed-bed packed reactor. The optimum temperature for NO reduction was found at 350 degree C for both fresh and sulfated catalysts. The properties for simultaneous removal of SO sub(2) and NO by the sol-gel-derived CuO/ gamma -Al sub(2)O sub(3) sorbents were studied using simulated dry flue gas. The optimum operating temperature for the combined deSO sub(2)/deNO operations was identified at 350 degree C. At the space velocity of 5200 h super(-1) and 350 degree C, a fixed-bed reactor packed with the 7.9 wt% CuO/ gamma -Al sub(2)O sub(3) sorbent prepared by the sol-gel method offers SO sub(2) sorption capacity of 2.3 mmol g super(-1) and NO conversion of 92% with a dry simulated flue gas as the feed. Under these experimental conditions, the sol-gel derived sorbents/catalysts have comparable efficiency for removal of SO sub(2) and NO sub(x) as their commercial counterparts. The significantly higher crush strength of the sol-gel derived sorbents/catalysts make them very promising for their use in the copper oxide process for combined removal of SO sub(2) and NO sub(x) from flue gas in a single unit operation.

The difficulties associated with solving RE numerically are well known. Most discretization approaches for RE lead to nonlinear systems that are large and difficult to solve. The solution of nonlinear systems for steady-state problems can be particularly challenging, since a good initial guess for the steady-state solution is often hard to obtain, and the resulting linear systems may be poorly scaled. Common approaches like Picard iteration or variations of Newton's method have their advantages but perform poorly with standard globalization techniques under certain conditions. Pseudo-transient continuation has been used in computational fluid dynamics for some time to obtain steady-state solutions for problems in which Newton's method with standard line-search strategies fails. Here, we examine the use of pseudo-transient continuation as well as Newton's method combined with standard globalization techniques for steady-state problems in heterogeneous domains. We investigate the methods' performance with direct and preconditioned Krylov iterative linear solvers. We then make recommendations for robust and efficient approaches to obtain steady-state solutions for RE under a range of conditions. Abstract Copyright (2003) Elsevier, B.V.

The results of this analysis demonstrate the utility of the scheme where more than 4800 data points collected on multiple measurement profiles have been inverted simultaneously. The resulting image clearly detects the buried waste; when receiver profiles cross pit boundaries, the image maps the lateral extent of the pit. However, the base of the pit is poorly resolved, and depends upon the starting model used to launch the inversion. Hence, critical information on whether contamination is leaching into a resistive gravel bed lining the base of the pit, as well as the deeper geological horizons consisting of brown coal, clay, and tertiary sands, is inconclusive. Nevertheless, by incorporating within the inversion process a priori information of the background media that is host to the waste, sharper images of the base of the pit are obtained, which are in good agreement with borehole data. The 3D analysis applied in this paper overcomes previous limitations in the radio magnetotelluric (RMT) method using 2D data analysis and inversion. With 3D analysis, it is unnecessary to make assumptions regarding geological strike, and near-surface statics can be accommodated in both source polarizations. Our findings also indicate that 2D MT interpretation can overestimate the pit's depth extent. This may lead to the erroneous conclusion that the geological horizons beneath the pit have been contaminated.

To address this problem, a new class of preconditioners has recently been proposed which is based on a Helmholtz decomposition of the electric field in the low induction number (LIN) regime. This paper further develops that idea and introduces a LIN preconditioner which can be applied to problems characterized by a fully generalized anisotropic medium. Included are sample calculations demonstrating a reduction by two orders of magnitude in the number of "quasi-minimal residual" iterates and a speedup by a factor of approximately four in the solution time for one forward calculation. Also included are results previously unobtainable by standard Jacobi preconditioning for simulating multicomponent induction sonde response in a horizontal well within a crossbedded formation.

As in so much of the world, access to fresh water is an increasingly critical issue in the southwestern United States. Growth in the Southwest has led to increased demand for water and to unsustainable water management practices, resulting in falling water tables with ground subsidence and associated building and utility damage, and reductions in surface water and groundwater quality and availability.

The goal in developing such a plan is more widespread use of desalination technology in water-scarce regions. An executive committee of 11 desalination experts from the public and private sectors was formed to develop a consensus on areas of desalination research and development that may lead to technological solutions to the water supply challenges facing the United States. The committee's conclusions are presented in a report titled "Desalination and Water Purification Technology Roadmap - A Report of the Executive Committee," published in January 2003 by the U.S. Bureau of Reclamation. The following article summarizes some of the non-technical points in the Roadmap.

Enumerating molecules from their extended valence sequences. AN - 73302772; 12767130 AB - We present a new algorithm that enumerates molecular structures matching a predefined extended valence sequence or signature. The algorithm can construct molecular structures composed of about 50 non-hydrogen atoms in CPU seconds time scale. The algorithm is run to produce all molecular structures matching the binding affinities (IC(50)) of some HIV-1 protease inhibitors. The algorithm is also used to compute the degeneracy, or the number of molecular structures, corresponding to a given signature. Signature degeneracy is systematically studied for varying signature heights on four molecular series, alkanes, alcohols, fullerene-type structures, and peptides. Signature degeneracy is compared with similar results obtained with popular topological indices (TIs). As a general rule, we find that signature degeneracy decreases as the signature height increases. We also find that alkanes, alcohols, and fullerene-type structures comprising n non-hydrogen atoms are uniquely characterized by signatures of height n/4, while peptides up to 4000 amino acids can be singled out with signatures of heights as small as 2 and 3.

Using extended valence sequences in QSAR and QSPR studies. AN - 73295465; 12767129 AB - We present a new descriptor named signature based on extended valence sequence. The signature of an atom is a canonical representation of the atom's environment up to a predefined height h. The signature of a molecule is a vector of occurrence numbers of atomic signatures. Two QSAR and QSPR models based on signature are compared with models obtained using popular molecular 2D descriptors taken from a commercially available software (Molconn-Z). One set contains the inhibition concentration at 50% for 121 HIV-1 protease inhibitors, while the second set contains 12865 octanol/water partitioning coefficients (Log P). For both data sets, the models created by signature performed comparable to those from the commercially available descriptors in both correlating the data and in predicting test set values not used in the parametrization. While probing signature's QSAR and QSPR performances, we demonstrates that for any given molecule of diameter D, there is a molecular signature of height h 90% of total mineral surface areas. Surface chemistry, ion sorption, and the related geochemical reactions within nanopores can be significantly modified by a nanometer-scale space confinement. As the pore size is reduced to a few nanometers, the difference between surface acidity constants (Delta pK = pK (sub 2) -pK (sub 1) ) decreases, giving rise to a higher surface charge density on a nanopore surface than that on an unconfined mineral-water interface. The change in surface acidity constants results in a shift of ion sorption edges and enhances ion sorption on nanopore surfaces. Also, the water activity in a nanopore is greatly reduced, thus increasing the tendency for inner sphere complexation and mineral precipitation. All these effects combine to preferentially enrich trace elements in nanopores, as observed in both field and laboratory studies. The work reported here sheds new light on such fundamental geochemical issues as the irreversibility of ion sorption and desorption, the bioavailability of subsurface contaminants, and the enrichment of trace metals in ore deposits, as well as the kinetics of mineral dissolution and/or precipitation.

This is problematic in that it has created extensive flooding. The purpose of the study was to determine the erosion and transport potential of the sediments obstructing the flow. This was done using a unique Mobile High Shear Stress flume developed by Sandia's Carlsbad Programs Group for the US Army Corps of Engineers. The flume measures in-situ sediment erosion properties at shear stresses ranging form normal flow to flood conditions for a variable depth sediment core. The flume is in a self-contained trailer that can be placed on site in the field. Erosion rates and sediment grain size distributions were determined from sediment samples collected in and around the obstruction. This data was used to characterize the erosion potential of the sediments of concern.

For the first time, the relative importance of ReO (sub 4) (super -) and the neutral rhenium species, Re(OH) (sub 4) (super 0) , is thermodynamically modeled in anoxic environments at ambient temperature where ReS (sub 2) or its solid solution(s) is likely to control the solubility. This thermodynamic model suggests that ReO (sub 4) (super -) is an insignificant species in anoxic environments. In comparison to observed total rhenium concentrations in anoxic waters (from approximately 3 to approximately 30 pmol/kg), the contribution from ReO (sub 4) (super -) would be less than 10 (super -8) ppb ( approximately 4X10 (super -5) pmol/kg). In contrast, the neutral rhenium species is an important species in anoxic environments. At Sigma H (sub 2) S = 10 (super -4) molal, 10 (super -2) ppb ( approximately 40 pmol/kg) of Re(OH) (sub 4) (super 0) can exist in equilibrium with ReS (sub 2) in the HS (super -) field at a pH of about 9 or under the oxygen fugacity conditions imposed by the HS (super -) /SO (sub 4) (super 2-) redox couple, demonstrating its importance in anoxic environments. Applications of the present study to the Black Sea indicate that rhenium concentrations in the anoxic water column at depths ranging from 105 to approximately 390 m can be successfully modeled as Re(OH) (sub 4) (super 0) , implying that the dominant species in solution may be Re(OH) (sub 4) (super 0) .

The tests were conducted to (1) test a conceptual radionuclide transport model for saturated, fractured tuffs near Yucca Mountain and (2) obtain transport parameter estimates for predictive modeling of radionuclide transport. The differences between the responses of the two nonsorbing tracers and the sorbing tracer (when normalized to injection masses) were consistent with a dual-porosity transport system in which matrix diffusion was occurring. The concentration attenuation of the sorbing tracer relative to the nonsorbing tracers suggested that diffusion occurred primarily into matrix pores, not simply into stagnant water within the fractures. The K (sub d) values deduced from the lithium responses were generally larger than K (sub d) values measured in laboratory batch sorption tests using crushed C-wells cores. This result supports the use of laboratory-derived K (sub d) values for predicting sorbing species transport at the site, as the laboratory K (sub d) values would result in underprediction of sorption and hence conservative transport predictions. The tracer tests also provided estimates of effective flow porosity and longitudinal dispersivity at the site. The tests clearly demonstrated the advantages of using multiple tracers of different physical and chemical characteristics to distinguish between alternative conceptual transport models and to obtain transport parameter estimates that are better constrained than can be obtained using only a single tracer or using multiple nonsorbing tracers without a sorbing tracer.

The simulation modeling approach is based on a continuum formulation of coupled multiphase fluid flow and tracer transport processes through fractured porous rock using a dual-continuum concept. Infiltration rate calibrations were performed using the porewater chloride data. Model results of chloride distributions were improved in matching the observed data with the calibrated infiltration rates. Statistical analyses of the frequency distribution for overall percolation fluxes and chloride concentration in the unsaturated zone system demonstrate that the use of the calibrated infiltration rates had an insignificant effect on the distribution of simulated percolation fluxes but significantly changed the predicted distribution of simulated chloride concentrations. An analytical method was also applied to model transient chloride transport. The method was verified by three-dimensional simulation results to be capable of capturing major chemical transient behavior and trends. Effects of lateral flow in the Paintbrush nonwelded unit on percolation fluxes and chloride distribution were studied by three-dimensional simulations with increased horizontal permeability. The combined results from these model calibrations furnish important information for the UZ model studies, contributing to performance assessment of the potential repository.

The analysis considers changes in rock mass porosity, permeability, and capillary pressure caused by rock deformations during drift excavation, as well as those caused by thermomechanically induced rock deformations after emplacement of the heat-generating waste. The analysis consists of a detailed calibration of coupled hydraulic-mechanical rock mass properties against field experiments, followed by a prediction of the coupled thermal, hydrologic, and mechanical behavior around a potential repository drift. For the particular problem studied and parameters used, the analysis indicates that the stress-induced permeability changes will be within one order of magnitude and that these permeability changes do not significantly impact the overall flow pattern around the repository drift.

The microbial growth results from the introduction of water, ground support, and waste package materials into the deep unsaturated rock. The simulations, which spanned 1 million years, were accomplished using a newly developed computer code, Microbial Impacts to the Near-Field Environment Geochemistry (MING). MING uses environmental thresholds for limiting microbial growth to temperatures below 120 degrees C and above relative humidities of 90% in repository drifts. Once these thresholds are met, MING expands upon a mass balance and thermodynamic approach proposed by McKinley et al. [FEMS Microbiol. Rev. 20 (1997) 545] by using kinetic rates to supply constituents from design materials and constituent fluxes including solubilized rock components into the drift to perform two separate mass balance calculations as a function of time. The first (nutrient limit) assesses the available nutrients (C, N, P and S) and calculates how many microorganisms can be produced based on a microorganism stoichiometry of C (sub 160) (H (sub 280) O (sub 80) )N (sub 30) P (sub 2) S. The second (energy limit) calculates the energy available from optimally combined redox couples for the temperature and pH at that time. This optimization maximizes those reactions that produce >15 kJ/mol (limit on useable energy) using an iterative linear optimization technique. The final available energy value is converted to microbial mass at a rate of 1 kg of biomass (dry weight) for every 64 MJ of energy. These two values (nutrient limit and energy limit) are then compared and the smaller value represents the number of microorganisms that can be produced over a specified time. MING can also be adapted to investigate other problems of interest as the model can be used in saturated and unsaturated environments and in laboratory situations to establish microbial growth limitations. Other projected uses include investigations of contaminated locations where monitored natural attenuation or engineered bioremediation could be employed.

The model is based on a two-dimensional, cross-sectional, dual-permeability model of the unsaturated zone at Yucca Mountain and uses a stochastic approach to investigate the effect of small-scale heterogeneous features. The studies were conducted using one uniform fracture permeability case, three realizations of stochastically generated fracture permeability, one discrete permeability feature case, and one increased ambient liquid flux case. In all cases, the models predict that completely dry drift conditions will develop above and below the drift in 10-100 years and remain dry for 1000-2000 years. During this period, the models predict no seepage into drifts, although liquid flux above the drifts and within the drift pillars may increase by up to two orders of magnitude above ambient flux. This is because the heat released by the emplaced waste is sufficient to vaporize liquid flux of one to two orders of magnitude higher than present-day ambient flux for over 1000 years. The results also show that unsaturated zone thermal-hydrological (TH) models with uniform layer permeability can adequately predict the evolution of seepage and moisture distribution in the rock mass surrounding the repository drifts. The models further show that although variability in fracture permeability may focus and enhance liquid flow in regions of enhanced liquid saturation (due to condensation above the drifts), vaporization and vapor diffusion can maintain a dry environment within the drifts for thousands of years.

The most straightforward approach is to account for the 3-D drift- and mountain-scale dimensionality all within a single monolithic thermohydrologic model. This approach is too computationally expensive to be a viable simulation tool capable of addressing all waste-package locations in the repository. The Multiscale Thermohydrologic Model (MSTHM) is a computationally efficient alternative to addressing these modeling issues. In this paper, we describe the principal calculation stages to predict temperature, relative humidity, and liquid-saturation, as well as other thermohydrologic variables, in the drifts and in the host rock. Using a three-drift repository example (which is a scaled-down version of the proposed repository), we demonstrate the validity of the MSTHM approach against a nested monolithic thermohydrologic model.

Seepage is a key factor affecting the performance of the potential nuclear-waste repository at Yucca Mountain, Nevada. Three-dimensional numerical models were developed to simulate field tests in which water was released from boreholes above excavated niches. Data from air-injection tests were geostatistically analyzed to infer the heterogeneous structure of the fracture permeability field. The heterogeneous continuum model was then calibrated against the measured amount of water that seeped into the opening. This approach resulted in the estimation of model-related, seepage-specific parameters on the scale of interest. The ability of the calibrated model to predict seepage was examined by comparing calculated with measured seepage rates from additional experiments conducted in different portions of the fracture network. We conclude that an effective capillary strength parameter is suitable to characterize seepage-related features and processes for use in a prediction model of average seepage into potential waste-emplacement drifts.

In this study, parallel computing techniques, as implemented into the TOUGH2 code, are applied in large-scale numerical simulations on a distributed-memory parallel computer. The modeling study has been conducted using an over-1-million-cell three-dimensional numerical model, which incorporates a wide variety of field data for the highly heterogeneous fractured formation at Yucca Mountain. The objective of this study is to analyze the impact of various surface infiltration scenarios (under current and possible future climates) on flow through the UZ system, using various hydrogeological conceptual models with refined grids. The results indicate that the 1-million-cell models produce better resolution results and reveal some flow patterns that cannot be obtained using coarse-grid modeling models.

The results are based on a numerical model of site-scale saturated zone beneath Yucca Mountain. This model is used for performance assessment predictions of radionuclide transport and to guide future data collection and modeling activities. The numerical model is calibrated by matching available water level measurements using parameter estimation techniques, along with more informal comparisons of the model to hydrologic and geochemical information. The model software (hydrologic simulation code FEHM and parameter estimation software PEST) and model setup allows for efficient calibration of multiple conceptual models. Until now, the Large Hydraulic Gradient has been simulated using a low-permeability, east-west oriented feature, even though direct evidence for this feature is lacking. In addition to this model, we investigate and calibrate three additional conceptual models of the Large Hydraulic Gradient, all of which are based on a presumed zone of hydrothermal chemical alteration north of Yucca Mountain. After examining the heads and permeabilities obtained from the calibrated models, we present particle pathways from the potential repository that record differences in the predicted groundwater flow regime. The results show that Large Hydraulic Gradient can be represented with the alternate conceptual models that include the hydrothermally altered zone. The predicted pathways are mildly sensitive to the choice of the conceptual model and more sensitive to the quality of calibration in the vicinity on the repository. These differences are most likely due to different degrees of fit of model to data, and do not represent important differences in hydrologic conditions for the different conceptual models.

As part of an ongoing effort to evaluate thermal-hydrological-chemical (THC) effects on flow in fractured media, we performed a laboratory experiment and numerical simulations to investigate mineral dissolution and precipitation under anticipated temperature and pressure conditions in the repository. To replicate mineral dissolution by vapor condensate in fractured tuff, water was flowed through crushed Yucca Mountain tuff at 94 degrees C. The resulting steady-state fluid composition had a total dissolved solids content of about 140 mg/l; silica was the dominant dissolved constituent. A portion of the steady-state mineralized water was flowed into a vertically oriented planar fracture in a block of welded Topopah Spring Tuff that was maintained at 80 degrees C at the top and 130 degrees C at the bottom. The fracture began to seal with amorphous silica within 5 days. A 1-D plug-flow numerical model was used to simulate mineral dissolution, and a similar model was developed to simulate the flow of mineralized water through a planar fracture, where boiling conditions led to mineral precipitation. Predicted concentrations of the major dissolved constituents for the tuff dissolution were within a factor of 2 of the measured average steady-state compositions. The mineral precipitation simulations predicted the precipitation of amorphous silica at the base of the boiling front, leading to a greater than 50-fold decrease in fracture permeability in 5 days, consistent with the laboratory experiment. These results help validate the use of a numerical model to simulate THC processes at Yucca Mountain. The experiment and simulations indicated that boiling and concomitant precipitation of amorphous silica could cause significant reductions in fracture porosity and permeability on a local scale. However, differences in fluid flow rates and thermal gradients between the experimental setup and anticipated conditions at Yucca Mountain need to be factored into scaling the results of the dissolution/precipitation experiments and associated simulations to THC models for the potential Yucca Mountain repository.

Analyses of samples of only a few milliliters of pore water extracted by uniaxial or triaxial compression and by ultracentrifugation methods from adjacent core samples are generally in agreement, within the analytical error of 10% to 15%. However, the values of silica for water obtained by ultracentrifugation are consistently lower than values for water obtained by compression. The larger concentrations probably are due to localized pressure solution of silicate minerals during compression. The shallower water from core in borehole USW SD-6 was extracted from nonwelded units collectively referred to as the Paintbrush Tuff nonwelded (PTn). The deeper water was from core in both boreholes USW SD-6 and USW WT-24 in the nonwelded units referred to as the Calico Hills nonwelded (CHn). Significant differences in mean dissolved-ion concentrations in pore water between the PTn and CHn are (1) decreases in Ca, Mg, SO (sub 4) , and NO (sub 3) and (2) increases in HCO (sub 3) and (Na+K)/(Ca+Mg) ratios. The decrease in NO (sub 3) and the increase in HCO (sub 3) could be the result of denitrification through the oxidation of organic matter. The decrease in Ca and associated increase in (Na+K)/(Ca+Mg) is the result of ion exchange with zeolites in the CHn in borehole USW WT-24. This effect is not nearly as pronounced in borehole USW SD-6, probably reflecting a smaller amount of zeolitization of the CHn in USW SD-6. Geochemical calculations using the PHREEQC code indicate that the pore water from both boreholes USW SD-6 and USW WT-24 is uniformly undersaturated in anhydrite, gypsum, and amorphous silica, but supersaturated in quartz and chalcedony. The saturation of calcite, aragonite, sepiolite, and dolomite is more variable from sample to sample.

During the experiments, changes in moisture content were monitored within the test bed, and a slot excavated below the test bed was visually inspected for seepage. Our field tests suggest that the dry porous PTn matrix is capable of attenuating episodic percolation fluxes in localized areas (such as around faults) where fast flow would be expected to dominate. Once wetted, the matrix is able to retain the moisture over a period of months. As saturation increases in the matrix, less water imbibes along the fault and more water travels farther along the fault. From this observation, we infer that a sequence of infiltration events separated by periods of up to a few months could convey water over increasing distances along the fault.

These include a Higher-Temperature Operating Mode (HTOM), which results in a localized boiling zone around each emplacement drift, and a Lower-Temperature Operating Mode (LTOM), which always maintains sub-boiling temperatures throughout the repository. The HTOM places all waste packages nearly end to end, making the lineal power density greater than in the LTOM. The lower lineal power density in the LTOM was achieved by placing some waste packages farther apart (which results in a larger repository footprint), and through an increased reliance on pre-closure ventilation to remove the waste-package-generated heat. We focus on temperature T and relative humidity RH at the waste-package and drift-wall surfaces, and on in-drift evaporation. In general, HTOM temperatures are greater than corresponding LTOM temperatures, exhibit similar spatial variability and have a stronger dependence on infiltration flux. The duration of RH reduction on waste packages is similar for the LTOM and HTOM. A major difference between the LTOM and HTOM is the lower waste-package temperature at any given value of waste-package RH for the LTOM. Waste-package temperatures in the LTOM, by design, remain below approximately 85 degrees C; the absence of RH reduction arising from host-rock dryout causes waste-package RH to remain above about 40%. The HTOM waste packages experience higher temperatures and correspondingly lower RH conditions as a result of RH reduction arising from host-rock dryout. For most of the repository area, the HTOM delays the potential onset of gravity-driven seepage compared to the LTOM (as indicated by the duration of boiling at the drift wall). Boiling conditions in the HTOM also delays the onset of capillary-driven seepage into the granular invert, causing the HTOM to have less evaporation in the invert during the first 800-1500 years than the LTOM; subsequent evaporation rates are higher in the HTOM, due to the higher power density.

However, zeolitically altered areas are lower in permeability than unaltered regions, which raises the possibility that contaminants might bypass the sorptive zeolites. The relationship between hydrologic and chemical properties must be understood to predict the transport of radionuclides through zeolitically altered areas. In this study, we incorporate mineralogical information into an unsaturated zone transport model using geostatistical techniques to correlate zeolitic abundance to hydrologic and chemical properties. Geostatistical methods are used to develop variograms, kriging maps, and conditional simulations of zeolitic abundance. We then investigate, using flow and transport modeling on a heterogeneous field, the relationship between percent zeolitic alteration, permeability changes due to alteration, sorption due to alteration, and their overall effect on radionuclide transport. We compare these geostatistical simulations to a simplified threshold method in which each spatial location in the model is assigned either zeolitic or vitric properties based on the zeolitic abundance at that location. A key conclusion is that retardation due to sorption predicted by using the continuous distribution is larger than the retardation predicted by the threshold method. The reason for larger retardation when using the continuous distribution is a small but significant sorption at locations with low zeolitic abundance. If, for practical reasons, models with homogeneous properties within each layer are used, we recommend setting nonzero K (sub d) s in the vitric tuffs to mimic the more rigorous continuous distribution simulations. Regions with high zeolitic abundance may not be as effective in retarding radionuclides such as Neptunium since these rocks are lower in permeability and contaminants can only enter these regions through molecular diffusion.

However, the usefulness of this approach can be questioned in terms of its adequacy for representing fingering flow and transport in unsaturated fractured rock. The continuum approach thus needs to be evaluated carefully by comparing simulation results with field observations directly related to unsaturated flow and transport processes. This paper reports on such an evaluation, based on a combination of model calibration and prediction, using data from an infiltration test carried out in a densely fractured rock within the unsaturated zone of Yucca Mountain, Nevada. Comparisons between experimental and modeling results show that the continuum approach may be able to capture important features of flow and transport processes observed from the test. The modeling results also show that matrix diffusion may have a significant effect on the overall transport behavior in unsaturated fractured rocks, which can be used to estimate effective fracture-matrix interface areas based on tracer transport data. While more theoretical, numerical, and experimental studies are needed to provide a conclusive evaluation, this study suggests that the continuum approach is useful for modeling flow and transport in unsaturated, densely fractured rock.

At several locations, the measured values of (super 36) Cl/Cl ratios for salts leached from rock samples are high enough to provide strong evidence that at least a small component of bomb-pulse (super 36) Cl, fallout from atmospheric testing of nuclear devices in the 1950s and 1960s, was measured, implying that some fraction of the water traveled from the ground surface through 200-300 m of unsaturated rock to the level of the ESF during the last 50 years. These data are analyzed here using a formal statistical approach based on log-linear models to evaluate alternative conceptual models for the distribution of such fast flow paths. The most significant determinant of the presence of bomb-pulse (super 36) Cl in a sample from the welded Topopah Spring unit (TSw) is the structural setting from which the sample was collected. Our analysis generally supports the conceptual model that a fault that cuts through the nonwelded Paintbrush tuff unit (PTn) that overlies the TSw is required in order for bomb-pulse (super 36) Cl to be transmitted to the sample depth in less than 50 years. Away from PTn-cutting faults, the ages of water samples at the ESF appear to be a strong function of the thickness of the nonwelded tuff between the ground surface and the ESF, due to slow matrix flow in that unit.

The modeling study is based on the current thermal-hydrological (TH) mountain-scale model, which uses a locally refined 2D north-south cross-section and dual-permeability numerical approach. The model provides a prediction of the mountain-scale TH response under the thermal-load scenario of 1.45 kW/m, while accounting for future climatic changes and the effects of drift ventilation. The TH simulation results show that ventilation of the repository drifts has a large impact on thermal-hydrologic regimes and moisture-flow conditions at the repository. In both cases, with and without ventilation, the TH model predicts dry or reduced liquid saturation near the drifts for over 1000 years, during which liquid flux through the drifts is reduced to either zero or less than the ambient flux. Without ventilation, the model predicts higher temperatures at the repository, but no major moisture redistribution in the UZ except in the areas very near the heated drifts.

The validation of such numerical codes can be accomplished by comparison of numerical simulations against appropriate analytical solutions. In this paper, we present analytical solutions for the reactive transport of N-member radionuclide chains (i.e., multiple species of radionuclides and their daughter species) through a discrete fracture in a porous rock matrix applying a system decomposition approach. We consider the transport of N-member radionuclide chains in a single-fracture-matrix system as a starting point to simulate more realistic and complex systems. The processes considered are advection along the fracture, lateral diffusion in the matrix, radioactive decay of multiple radionuclides, and adsorption in both the fracture and matrix. Different retardation factors can be specified for the fracture and matrix. However, all species are assumed to share the same retardation factors for the fracture and matrix, respectively. Although a daughter species may penetrate farther along the fracture than its parent species when a constant-concentration boundary condition is applied, our results indicate that all species retain the same transport speed in the fracture if a pulse of the first species is released into the fracture. This solution scheme provides a way to validate numerical computer codes of radionuclide transport in fractured rock, such as those being used to assess the performance of a potential nuclear-waste repository at Yucca Mountain.

Different periods of site characterization activities and prominent issues concerning the unsaturated zone (UZ) are summarized. Data collection activities have evolved from mapping of faults and fractures to estimation of percolation through tuff layers, and to quantification of seepage into drifts. Evaluation of discrete flow paths in drifts has led to fracture-matrix interaction and matrix diffusion tests over different scales. The effects of tuff interfaces and local faults are evaluated in fractured-welded and porous-nonwelded units. Mobilization of matrix water and redistribution of moisture are measured in thermal tests. Lessons learned from underground tests are used to focus on processes needed for additional quantification. Migration through the drift shadow zone and liquid flow through faults are two important issues that have evolved from current knowledge.

In situ experiments were conducted on a 10X10X7 m block comprising a layered Topopah Springs/Calico Hills formation with two imbedded faults. Tracer solution was continuously injected in eight parallel boreholes arranged on two horizontal planes. Twelve collection boreholes were emplaced perpendicular to the injection holes and were both horizontal and inclined. Solution samples were collected regularly using a sampling assembly consisting of an inverted membrane and sorbing-paper sampling pads. Comparisons between measurements and predictions show that, except for the occasional drops of concentrations observed in the field, the current model is able to capture the general characteristics of the system with varying levels of agreement using laboratory-measured mean hydraulic properties. Simulation results and field observations revealed a capillary-driven flow in the system. Good quantitative agreement is generally observed for near-field boreholes, however, this agreement deteriorates and the simulated solute concentration is underestimated at boreholes farther away from the injection points. Increasing the spatial resolution of the simulation improves the model predictions only to a limited extent. Scaling issues may need to be considered to describe flow and transport events, as the travel distance becomes large.

Drifts in which waste packages will be emplaced are subject to degradation in the form of rockfall from the drift ceiling, induced by stress-relief, seismic, or thermal effects. The objective of this study is to calculate seepage rates, for various drift-degradation scenarios and for different values of percolation flux, in the Topopah Spring middle nonlithophysal (Tptpmn) and the Topopah Spring lower lithophysal (Tptpll) units at Yucca Mountain. Seepage calculations are conducted by (1) defining a heterogeneous drift-scale permeability model with field data, (2) selecting calibrated parameters associated with the Tptpmn and Tptpll units, and (3) simulating seepage, based on detailed degraded-drift profiles obtained from a separate rock mechanics engineering analysis. The simulation results indicate (1) that the seepage threshold (i.e., the percolation flux at which seepage first occurs) is not significantly changed by drift degradation and (2) the degradation-induced increase in seepage above the threshold is influenced probably more by the shape of the cavity created by rockfall than by rockfall volume.

The analysis of infiltration rates measured at both sites showed three temporal scales of infiltration rate: (1) a macro-scale trend of overall decreasing flow, (2) a meso-scale trend of fast and slow motion exhibiting three-stage variations of the flow rate (decreasing, increasing, and [again] decreasing flow rate, as observed in soils in the presence of entrapped air), and (3) micro-scale (high frequency) fluctuations. Infiltration tests in the nonwelded unit at Alcove 4 indicate that this unit may effectively dampen episodic fast infiltration events; however, well-known Kostyakov, Horton, and Philip equations do not satisfactorily describe the observed trends of the infiltration rate. Instead, a Weibull distribution model can most accurately describe experimentally determined time trends of the infiltration rate. Infiltration tests in highly permeable, fractured, welded tuff at Alcove 6 indicate that the infiltration rate exhibits pulsation, which may have been caused by multiple threshold effects and water-air redistribution between fractures and matrix. The empirical relationships between the extrinsic seepage from fractures, matrix imbibition, and gravity drainage versus the infiltration rate, as well as scaling and self-similarity for the leading edge of the water front are the hallmark of the nonlinear dynamic processes in water flow under episodic infiltration through fractured tuff. Based on the analysis of experimental data, we propose a conceptual model of a dynamic fracture flow and fracture-matrix interaction in fractured tuff, incorporating the time-dependent processes of water redistribution in the fracture-matrix system.

These studies are based on two- and three-dimensional (2-D and 3-D) numerical models using site-specific parameters. The 2-D and 3-D models use high-resolution spatial discretization to explicitly include effects of discrete fractures with stochastically developed fracture permeabilities and a continuum approach. The permeability field is generated based on air permeability measurements at various scales. For most of the cases considered, uniform infiltration with different average rates (1-500 mm/year) is prescribed at the top of the model, while variability in outflow at the bottom of the model is used to evaluate the degree of flow focusing. In addition, scenarios involving nonuniform infiltration at the top boundary, different permeability correlation lengths and different flow-allocation schemes were analyzed. The modeling results obtained from all of the cases showed a remarkably similar flow-focusing pattern at the repository horizon. Furthermore, tracer transport simulation results also revealed additional features of focused flow and transport through the fracture network.

The model considers the flow of water, gas, and heat, plus reactions between minerals, CO (sub 2) gas, and aqueous species, and porosity-permeability-capillary pressure coupling for a dual permeability (fractures and matrix) medium. Two possible operating temperature modes are investigated: a "high-temperature" case with temperatures exceeding the boiling point of water for several hundred years, and a "low-temperature" case with temperatures remaining below boiling for the entire life of the repository. In both cases, possible seepage waters are characterized by dilute to moderate salinities and mildly alkaline pH values. These trends in fluid composition and mineral alteration are controlled by various coupled mechanisms. For example, upon heating and boiling, CO (sub 2) exsolution from pore waters raises pH and causes calcite precipitation. In condensation zones, this CO (sub 2) redissolves, resulting in a decrease in pH that causes calcite dissolution and enhances feldspar alteration to clays. Heat also enhances dissolution of wall rock minerals leading to elevated silica concentrations. Amorphous silica precipitates through evaporative concentration caused by boiling in the high-temperature case, but does not precipitate in the low-temperature case. Some alteration of feldspars to clays and zeolites is predicted in the high-temperature case. In both cases, calcite precipitates when percolating waters are heated near the drift. The predicted porosity decrease around drifts in the high-temperature case (several percent of the fracture volume) is larger by at least one order of magnitude than in the low temperature case. Although there are important differences between the two investigated temperature modes in the predicted evolution of fluid compositions and mineral alteration around drifts, these differences are largely within to the model uncertainty and the variability of water compositions at Yucca Mountain.

This monitoring activity is intended to establish the extent to which predicted behavior matches the actual response of the geological system to waste emplacement. To accomplish this goal, field measurements must be made at a spatial resolution that will determine whether the changes in parameters that are monitored conform to predicted evolutionary patterns. From the perspective of thermohydrological and geochemical parameters, key measurements will consider pore water compositional evolution and changes in matrix and fracture saturation in the near vicinity of waste emplacement tunnels. A massively parallel high performance computational platform (a 1200 processor IBM SP-2) was used to conduct three-dimensional, high resolution simulations to ascertain the spatial variability to be expected during a monitoring period. The results show that spatial variability in certain chemical parameters below waste emplacement tunnels provides robust targets for monitoring, but will require sampling on the scale of 10 s of centimeters in some locations, in order to rigorously test models. Chemical variability induced by relatively small changes in waste package heat output suggests that designing a monitoring program that will rigorously test model predictions will likely require high resolution, three-dimensional simulations of the "as-built" monitoring tunnels.

Effective performance of such a repository would rely on a number of natural and engineered barriers to isolate radioactive waste from the accessible environment. Groundwater beneath Yucca Mountain is the primary medium through which most radionuclides might move away from the potential repository. The saturated zone (SZ) system is expected to act as a natural barrier to this possible movement of radionuclides both by delaying their transport and by reducing their concentration before they reach the accessible environment. Information obtained from Yucca Mountain Site Characterization Project activities is used to estimate groundwater flow rates through the site-scale SZ flow and transport model area and to constrain general conceptual models of groundwater flow in the site-scale area. The site-scale conceptual model is a synthesis of what is known about flow and transport processes at the scale required for total system performance assessment of the site. This knowledge builds on and is consistent with knowledge that has accumulated at the regional scale but is more detailed because more data are available at the site-scale level. The mathematical basis of the site-scale model and the associated numerical approaches are designed to assist in quantifying the uncertainty in the permeability of rocks in the geologic framework model and to represent accurately the flow and transport processes included in the site-scale conceptual model. Confidence in the results of the mathematical model was obtained by comparing calculated to observed hydraulic heads, estimated to measured permeabilities, and lateral flow rates calculated by the site-scale model to those calculated by the regional-scale flow model. In addition, it was confirmed that the flow paths leaving the region of the potential repository are consistent with those inferred from gradients of measured head and those independently inferred from water-chemistry data. The general approach of the site-scale SZ flow and transport model analysis is to calculate unit breakthrough curves for radionuclides at the interface between the SZ and the biosphere using the three-dimensional site-scale SZ flow and transport model. Uncertainties are explicitly incorporated into the site-scale SZ flow and transport abstractions through key parameters and conceptual models.

Systematic measurements of calcite and opal coatings in the Exploratory Studies Facility (ESF) tunnel at the proposed repository horizon are used to estimate the volume of calcite at each site of calcite and/or opal deposition. By estimating the volume of water required to precipitate the measured volumes of calcite in the unsaturated zone, seepage rates of 0.005 to 5 liters/year (l/year) are calculated at the median and 95th percentile of the measured volumes, respectively. These seepage rates are at the low end of the range of seepage rates from recent performance assessment (PA) calculations, confirming the conservative nature of the performance assessment. However, the distribution of the calcite and opal coatings indicate that a much larger fraction of the potential waste packages would be contacted by this seepage than is calculated in the performance assessment.

The lithophysal rock is described as a tri-continuum medium, consisting of fractures, rock matrices, and cavities. In the conceptual model, fractures have homogeneous properties throughout and interact with rock matrices and cavities that have different permeabilities and porosities. Global flow occurs through the fracture network only, while rock matrices and cavities contain the majority of fluid storage and provide fluid drainage to the fractures. Interporosity flows between the triple media are described using a pseudosteady-state concept and the system is characterized by interporosity transmissivity ratios and storativity ratio of each continuum. Pressure behavior is analyzed by examining the pressure drawdown curves, the derivative plots, and the effects of the characteristic parameters. Typical pressure responses from fractures, matrices, and cavities are represented by three semilog straight lines; the transitions by two troughs below the stabilization lines in the derivative plots. The analytical solution to the proposed model is further verified using a numerical simulation. The analytical model has also been applied to a published field-buildup well test and is able to match the pressure buildup data.

The goal of the effort was to produce a computational model that can be coupled to the project's calibrated 3D site-scale flow model so that the results of that effort could be incorporated directly into the Total System Performance Assessment (TSPA) analyses. The transport model simulates multiple species (typically 20 or more) with complex time-varying and spatially varying releases from the potential repository. Water-table rise, climate-change scenarios, and decay chains are additional features of the model. A cell-based particle-tracking method was employed that includes a dual-permeability formulation, advection, longitudinal dispersion, matrix diffusion, and colloid-facilitated transport. This paper examines the transport behavior of several key radionuclides through the unsaturated zone using the calibrated 3D unsaturated flow fields. Computational results illustrate the relative importance of fracture flow, matrix diffusion, and lateral diversion on the distribution of travel times from the simulated repository to the water table for various climatic conditions. Results also indicate rapid transport through fractures for a portion of the released mass. Further refinement of the model will address several issues, including conservatism in the transport model, the assignment of parameters in the flow and transport models, and the underlying assumptions used to support the conceptual models of flow and transport in the unsaturated zone at Yucca Mountain.

Flow modeling and field testing have shown that not all flow encountering a drift will seep into the drift. The underlying reason for the diversion of unsaturated flow around a drift is that capillary forces in the fractures and matrix prevent water entry into the drift unless the capillary pressure in the rock decreases sufficiently to allow for gravity forces to overcome the capillary barrier. As a result of the capillary barrier effect, flow tends to be diverted around the drift, affecting the flow pattern beneath the drift. For some distance beneath the drift, water saturation and flux are reduced. This drift shadow zone is much more pronounced in the fractures than in the matrix due to dominance of gravity over capillary forces in the fractures. Moving downward, away from the drift, the shadow zone asymptotically re-equilibrates to the undisturbed flow conditions due to capillary forces. The behavior of radionuclide transport in this zone of reduced flow is investigated here because this will affect the amount of time required for radionuclides to penetrate the unsaturated zone. The delay of radionuclide movement in the geosphere is one aspect of the potential repository system that could limit public exposure to radioactive waste. The behavior of flow and transport is calculated using a two-dimensional, drift-scale dual-permeability model extending to nine drift diameters below the potential waste emplacement drift. The flow model is first compared with an analytical model for a single continuum. Then, the dual-continuum flow model is investigated with respect to drift-scale and mountain-scale property sets. Transport calculations are performed for a wide range of flow conditions and for different aqueous radionuclides and colloids. Findings indicate that transport times for dissolved or colloidal material released from a drift without seepage are several orders of magnitude longer than if the releases occurred in the undisturbed flow field. Furthermore, the calculations indicate that the transport rate for radionuclides released in the drift shadow is relatively insensitive to flow rates in the fractures, but is sensitive to the flow rate in the matrix.

A multilayer, one-dimensional analytical solution is presented for determining percolation flux from temperature data. Case studies have shown that the analytical solution agrees very well with results from the numerical code, TOUGH2. The results of the analysis yield percolation fluxes in the range from 0 to 20 mm/year for most of the deep boreholes. This range is in good agreement with the results of infiltration studies at Yucca Mountain. Percolation flux for the shallower boreholes, however, cannot be accurately determined from temperature data alone because large gas flow in the shallow system alters the temperature profiles. Percolation-flux estimates for boreholes located near or intersecting major faults are significantly higher than those for other boreholes. These estimates may be affected by gas flow in the faults.

One objective of the field tests is to determine how well field-scale reactive transport can be predicted using transport parameters derived from laboratory experiments. This paper describes several laboratory lithium batch sorption and column transport experiments that were conducted using ground water and alluvium obtained from the site of the planned field tests. In the batch experiments, isotherms were determined over 2.5 orders of magnitude of lithium concentrations, corresponding to the range expected in the field tests. In addition to measuring equilibrium lithium concentrations, concentrations of other cations, namely Na (super +) , K (super +) , and Ca (super 2+) , were measured in the batch tests to determine Li (super +) -exchangeable equilibria. This information was used in conjunction with alluvium cation exchange capacity measurements to parameterize a three-component cation-exchange model (EQUIL) that describes lithium sorption in the alluvium system. This model was then applied to interpret the transport behavior of lithium ion in saturated alluvium column tests conducted at three different lithium bromide injection concentrations. The concentrations were selected such that lithium ion either dominated, accounted for a little over half, or accounted for only a small fraction of the total cation equivalents in the injection solution. Although tracer breakthrough curves differed significantly under each of these conditions, with highly asymmetric responses occurring at the highest injection concentrations, the three-component cation-exchange model reproduced the observed transport behavior of lithium and the other cations in each case with a similar set of model parameters. In contrast, a linear K (sub d) -type sorption model could only match the lithium responses at the lowest injection concentration. The three-component model will be used to interpret the field tests, with the expectation that it will help refine estimates of effective flow porosity, particularly if the lithium response curves are asymmetric.

The Drift Scale Test (DST), intended for acquiring such an understanding of these processes, has generated a huge volume of temperature and moisture redistribution data. Sophisticated thermal-hydrological (TH) conceptual models have yielded a good fit between simulation results and those measured data. However, some uncertainties in understanding the TH processes associated with the DST still exist. This paper evaluates these uncertainties and provides quantitative estimates of the range of these uncertainties. Of particular interest for the DST are the uncertainties resulting from the unmonitored loss of vapor through an open bulkhead of the test. There was concern that the outcome from the test might have been significantly altered by these losses. Using alternative conceptual models, we illustrate that predicted mean temperatures from the DST are within 1 degrees C of the measured mean temperatures through the first 2 years of heating. The simulated spatial and temporal evolution of drying and condensation fronts is found to be qualitatively consistent with measured saturation data. Energy and mass balance computation shows that no more than 13% of the input energy is lost because of vapor leaving the test domain through the bulkhead. The change in average saturation in fractures is also relatively small. For a hypothetical situation in which no vapor is allowed to exit through the bulkhead, the simulated average fracture saturation is not qualitatively different enough to be discerned by measured moisture redistribution data. This leads us to conclude that the DST, despite the uncertainties associated with open field testing, has provided an excellent understanding of the TH processes.

The abundance of fractures and the spatial variability in their hydraulic properties, along with the heterogeneity within lithologic formations, make evaluation of unsaturated processes occurring within the potential repository horizon complex. Fracture mapping and field testing show that fractures are well connected, yet considerable variation is seen within and between units comprising the potential repository horizon with regard to fracture trace length, spacing, permeability, and capillarity. These variations have important implications for the distribution and movement of water and solutes through the unsaturated zone. Numerical models designed to assess such phenomena as unsaturated flow, transport, and coupled thermal-hydrological processes each require their own conceptual model for fracture networks, in order to identify the subset of all fractures that is relevant to the particular study. We evaluate several process-dependent conceptual models for fractures and identify the relevant fracture subsets related to these processes.

AN - 73242256; 12714318 AB - Thermally induced natural convection from the heat produced by emplaced waste packages is an important heat and mass transfer mechanism within the Yucca Mountain Project (YMP) drifts. Various models for analyzing natural convection have been employed. The equivalent porous medium approach using Darcy's law has been used in many YMP applications. However, this approach has questionable fidelity, especially for turbulent flow conditions. Computational fluid dynamics (CFD), which is based on the fundamental Navier-Stokes equations, is currently being evaluated as a technique to calculate thermally induced natural convection in YMP. Data-model comparisons for turbulent flow conditions show good agreement of CFD predictions with existing experiments including YMP-specific data.

AN - 73235212; 12714302 AB - Evaluation of radionuclide transport in the saturated zone (SZ) to the accessible environment is an important component of performance assessment for the proposed radioactive waste repository at Yucca Mountain. Simulations of radionuclide migration in the SZ have been performed using the calibrated three-dimensional (3-D) SZ site-scale flow and transport model. An innovative particle-tracking method was used to simulate transport that includes the processes of advection, dispersion, matrix diffusion, and sorption. The uncertainties in groundwater flow and radionuclide transport were quantitatively evaluated to develop uncertainty distributions for key model parameters, and multiple realizations of the SZ system were simulated using the SZ site-scale model. The results of multiple realizations of radionuclide transport indicate significant aggregate uncertainty in transport times through the SZ. The simulated radionuclide mass breakthrough curves in the SZ have been coupled with other components of the repository system in Total System Performance Assessment (TSPA) analyses and constitute the means by which uncertainty in the SZ is incorporated into regulatory analyses. Regression analysis has been used to determine the sensitivity of radionuclide transport simulation results to the uncertainty of individual model input parameters. Results of the sensitivity analysis indicate that median radionuclide transport times were dominantly controlled by uncertainty in the specific discharge in the SZ, with sorption and retardation in the alluvium playing important roles for some radionuclides.

Two different stochastic continuum models (SCM) that define the spatial variability of permeability are inferred from the observed fracture characteristics and the measured permeabilities. These models are created with a combination of indicator geostatistics and boolean simulation that allow for modeling different correlation lengths and anisotropy ratios at different permeability thresholds as well as the inclusion of large, high-permeability features. Longitudinal and transverse (horizontal and vertical) dispersion through the permeability realizations is evaluated for both distributed and focused source geometries using groundwater flow and streamline particle tracking. These numerical results are compared to behavior predicted by an analytical solution and to dispersivities estimated by an expert panel. Early time transport results are significantly non-Gaussian due to the strong heterogeneity of the fractured medium. At late times, travel distances of 23 correlation lengths, the longitudinal and transverse horizontal dispersivity results are well approximated by the analytical solution and the expert elicitation estimates. The calculated transverse vertical dispersivity values are smaller than those estimated from the analytical solution. Inclusion of high-permeability features of the same size as the model domain with a distributed planar source creates extreme values of the longitudinal and transverse horizontal dispersivity.

These conditions are frequently encountered in urban highways, airports, parking structures and so forth. Ventilation configurations tested included ceiling curtains and jets. A simple 2D geometry without artificial ventilation was used as a base case together with a worst-case flow scenario that assumed no transverse ambient wind flow. The base-case simulations were compared to simulations for various auxiliary ventilation alternatives. The simulations demonstrate that ventilation is necessary to effectively minimize peak ambient concentrations in covered roadways. Auxiliary overhead ventilation ports are found to result in the most dramatic improvement in pollutant concentrations. The simulations also indicate that regions of low velocity and vortex-type flow patterns with flow reversals are characteristic of situations with very high values of peak pollutant concentrations.

We designed and conducted a flow visualization experiment to investigate capillary barrier performance in this context. A two-dimensional, thin slab, test system replicated the physical emplacement drift to one-quarter scale (1.4-m diameter) and included the simulated drift wall, waste canister, pedestal, capillary barrier backfill, and host-rock fracture system. Water was supplied at the top of the simulated drift and allowed to discharge by way of wicks located along the left wall of the cell (simulated fractures) or by a gravity drain at the bottom of the right side (simulated impermeable rock with floor drain). Photographs captured the migration of water and a blue dye tracer within the system, analytical balances measured the mass balance of water, while tensiometers measured the capillary pressure at numerous locations. Of particular concern to this test was the drainage of the capillary barrier, which terminates against the drift wall. We found that while the simulated fractures (left side) and drain (right side) each influenced the performance of the capillary barrier at early time, they had little differential affect at later times. Also of concern was the small disparity in capillary properties between the fine and coarse layer (limited by the need of a fine-grained material that would not filter into the coarse layer under dry conditions). While the capillary barrier was able to divert the majority of flow toward the edges of the system and away from the simulated waste canister, the barrier did not preclude flow in the coarse layer, which was noted to be visually wet next to the waste canister on day 92 and was continuing to take on water at termination on day 112.

This shortening was the result of compression of the strata between southward indentation of the San Juan uplift at the north edge of the basin and northward to northeastward indentation of the Zuni uplift from the south. Right-lateral strike-slip motion was concentrated at the eastern and western margins of the basin to form the Hogback monocline and the Nacimiento uplift at the same time. Small amounts of shear may have occurred along pre-existing basement faults within the basin as well. Vertical extension fractures, striking north-south to north northeast-south southwest (parallel to the Laramide maximum horizontal compressive stress) with local variations, formed in both Mesaverde and Dakota sandstones under this system, and are found in outcrops and in the subsurface. The less-mature Mesaverde sandstones typically contain relatively long and irregular vertical extension fractures, whereas the underlying quartzitic Dakota sandstones contain more numerous, shorter, sub-parallel, closely spaced extension fractures. Conjugate shear fractures in several orientations are also present locally in Dakota strata.

AN - 71610312; 16256496 AB - A novel technique is described to investigate buried polymer/sizing/substrate interfacial regions, in situ, by localizing a fluorescent probe molecule in the sizing layer. Epoxy functional silane coupling agent multilayers were deposited on glass microscope cover slips and doped with small levels of a fluorescently labeled silane coupling agent (FLSCA). The emission of the grafted FLSCA was dependent on the silane layer thickness, showing blue-shifted emission with decreasing thickness. The fluorescent results suggest that thinner layers were more tightly bound to the glass surface. The layers were also characterized by scanning electron microscopy, contact angle, and thermogravimetric analysis (TGA). When the FLSCA-doped silane layers were immersed in epoxy resin, a blue shift in emission occurred during resin cure, indicating the potential to study interfacial chemistry, in situ. Thicker silane layers exhibited smaller fluorescence shifts during cure, suggesting incomplete resin penetration into the thickest silane layers.

AN - 75729484; 14522192 AB - The polycyclic aromatic hydrocarbons (PAH) that contaminate soils at many industrial and government sites are resistant to natural biotic and abiotic degradation processes. The recalcitrant nature of these compounds may require aggressive chemical treatment to effectively remediate these sites. This study was conducted to assess the viability of permanganate oxidative treatment as a method to reduce PAH concentration in contaminated soils. Study results demonstrated a reduction in soil sorbed concentration for a mixture of six PAHs that included anthracene, benzo(a)pyrene, chrysene, fluoranthene, phenanthrene, and pyrene by potassium permanganate (KMnO4) oxidative treatment. The greatest reduction in soil concentration was observed for benzo(a)pyrene, pyrene, phenanthrene, and anthracene at 72.1, 64.2, 56.2, and 53.8%, respectively, in 30 min at a KMnO4 concentration of 160 mM. Minimal reductions in fluoranthene and chrysene concentration were observed at 13.4 and 7.8%, respectively, under the same conditions. A relative chemical reactivity order of benzo(a)pyrene>pyrene>phenanthrene>anthracene>fluoranthene>chrysene towards permanganate ion was observed. Aromatic sextet theory was applied to the degradation results to explain the highly variable and compound-specific chemical reactivity order. JF - Waste management (New York, N.Y.)

AN - 75714188; 14515020 AB - Cell membranes consist of a fluidic medium of lipids and proteins that organize into specific submicron scale structures for signaling and molecular trafficking processes. These organized molecular assemblies form as a result of the structure and chemistry of the membrane components as well as the interactions of those components with analytes from solution. Although considerable research has focused on the structure and chemistry of membrane components and their ability to form organized assemblies, less attention has been paid toward the influence that chemical recognition has upon membrane reorganization. This review focuses on the recognition and binding of metal ions, small molecules, polyelectrolytes, and proteins on model membrane systems to assess the effects of long- and short-range interactions upon the molecular organization of the membrane. Chemical recognition can induce dramatic changes on the membrane's phase transition temperature and the clustering or dispersion of membrane components.

Here we examine the ability of a genetic algorithm (GA) to update indicator variogram parameters defining the spatial correlation of the K field subject to minimizing differences between modeled and observed head values and also to minimizing the advective travel time across the model. The technique is presented on a test problem consisting of 83 K values randomly selected from 8649 gas-permeameter measurements made on a block of heterogeneous sandstone. Indicator variograms at the 10th, 40th, 60th and 90th percentiles of the cumulative log10 K distribution are used to describe the spatial variability of the log10 hydraulic conductivity data. For each threshold percentile, the variogram models are parameterized by the nugget, sill, anisotropic range values and the direction of principal correlation. The 83 conditioning data and the variogram models are used as input to a geostatistical indicator simulation algorithm. Stochastic realizations of the hydraulic conductivity field are created and these realizations reproduce the gross features of the true K field, but they are not adequate to reproduce the fine-scale structure of the true K field. A GA is used to adjust 16 variogram parameters (4 adjustable parameters per threshold percentile) by minimizing the difference between the heads measured by running a ground water flow model on the true field and the heads calculated on the stochastic hydraulic conductivity realizations as well as minimizing the advective travel time across the modeled K field. The GA is a stochastic search method that uses tournament selection, crossover, and mutation to mimic survival of the fittest and to evolve the best parameter values that meet the specified objectives and constraints. Results show that a GA can be used to optimize the variogram parameters subject to two different objectives and that the experimental variograms defined from a limited data set may not be the optimal variograms in terms of matching heads or minimizing travel time.

Hazardous waste sites contaminated with metals can be screened for the implementation of monitored natural attenuation on the basis of contaminant-specific soil chemical characteristics (i.e., K' (sub d) s, solubilities, and nonexchangeable sorbed fraction). Field cases are used to demonstrate the screening approach and to outline the primary considerations involved in accurately applying sequential extraction procedures to support the of MNA for site remediation. The results of these case studies provide strong evidence that site-specific screening and the use of sequential extraction procedures are effective methods for evaluating natural attenuation for metals impacted sites.

However, the lack of efficacious predictive dynamic models for joints hinders accurate prediction of their dynamic behavior. The goal of our work is to develop physics-based, reduced-order, finite element models that are capable of replicating the effects of joints on vibrating structures. The authors recently developed the so-called two-dimensional adjusted Iwan beam element (2-D AIBE) to simulate the hysteretic behavior of bolted joints in 2-D beam structures. Here, 2-D AIDE is extended to three-dimensional cases by formulating a three-dimensional adjusted Iwan beam element (3-D AIDE). Impulsive loading experiments arc applied to a jointed frame structure and a beam structure containing the same joint. The tome is subjected to excitation out of plane so that the joint is under rotation and single axis bending. By assuming that the rotation in the joint is linear elastic, the parameters of the joint associated with bending in the frame are identified from acceleration responses of the jointed beam structure, using a multi-layer feed-forward neural network (MLFF). Numerical simulation is then performed on the frame structure using the identified parameters. The good agreement between the simulated and experimental impulsive acceleration responses of the frame structure validates the efficacy of the presented 3-D AIBE, and indicates that the model can potentially be applied to more complex structural system with joint parameters identified from a relatively simple structure.

The T values show a strong relationship to depth with contributions from two additional factors: dissolution of halite from the upper part of the underlying Salado Formation, and distribution of halite in the Rustler. Three maps related to these factors improve our understanding of the processes involved in creating the T distribution. An elevation map of the Culebra shows the general regional eastward dip, which contributes to the depth factor, and two northwest-southeast-trending anticlines. Along the eastern margin of Nash Draw (a closed depression formed by dissolution and erosion), elevation contours are disrupted where the Culebra subsided as halite was removed from the upper Salado Formation. A map of the thickness between the Culebra and an upper Salado unit reveals pronounced decreases identified as the margin of dissolution of upper Salado halite. The dissolution margin underlies, and is the apparent control for, the escarpment on the eastern margin of Nash Draw. Rustler halite margins on the third map mainly indicate limits to saline facies tracts; they are also the most likely location for any post-depositional dissolution. The geologic data on these maps can be used to develop a quantitative model for predicting Culebra T. The data have also been used to select drilling and hydraulic-testing locations for an extensive field program, beginning in 2003.

The compressive structures consist of low-angle thrust faults meters to tens of meters in scale that have commonly been interpreted as post-depositional tectonic features. However, soft-sediment rather than brittle deformation textures in the rock and an absence of slickensides along planes of offset suggest that these strata were poorly lithified at the time of thrusting. Moreover, these structures are commonly overlain or truncated by undeformed strata that could only have been deposited after deformation. Smaller, low-angle dip-slip shear planes, common in the interbedded coals, may also be related to this syn-sedimentary, Laramide compression. At least one normal fault, striking perpendicular to the strike of the thrust faults, displays textures that also suggest motion prior to significant lithification. Structural modification of the strata during deposition may have diverted local drainage along the depositional strike and thus may have helped control the orientation of fluvial sandstone reservoirs in the basin.

The reservoir is extensively fractured so most of the permeability is a result of natural fractures. The assumption has always been that a regional set of fractures oriented approximately N50E have been responsible for fluid movement in Spraberry. However, over the years, unusual behavior has been noted that does not always conform to the presumed characteristics of the fracture system. For the first time in over 50 years of production, a horizontal core has been retrieved. Over 100 natural fractures were intersected out of approximately 300 feet of core. The average fracture spacing of 2.86 feet corroborated simulation studies that have always relied on a value of approximately 3 feet for fracture spacing in order to best match production data. However, the startling result that there are three natural fracture sets was also discovered from the horizontal core. The presence of multiple fracture sets explains some of the mysterious behavior cited in Spraberrry literature. The existence of three distinct natural fracture sets would probably never have been deduced from vertical core or existing information.

A controlled study was conducted at the HAZMAT Spill Center at the Nevada Test Site, where the sensor was tested under a range of temperature, moisture, and trichloroethylene (TCE) concentrations. The sensor responded rapidly when exposed to TCE placed in sand, and it also responded to decreases in TCE vapor concentration when clean air was vented through the system. Variations in temperature and water vapor concentration impacted baseline chemiresistor signals, but at high TCE concentrations the sensor response was dominated by the TCE exposure. Test results showed that the detection limit of the chemiresistor to TCE vapor in the presence of fluctuating environmental variables (i.e., temperature and water vapor concentration) was on the order of 1000 parts per million by volume, which is about an order of magnitude higher than values obtained in controlled laboratory environments. Automated temperature control and preconcentration is recommended to improve the stability and sensitivity of the chemiresistor sensor.

AN - 72728254; 12455949 AB - ICRP Publication 68 presents dose coefficients developed using systems of new models for the respiratory tract and metabolism of certain elements. The utility of these dose coefficients and associated models is limited without a method for calculating intake from bioassay results using the same models as in that publication. The calculation of a radionuclide intake requires values of expected fractions of the intake in bioassay samples collected at specific times after intake. The general system of models has been solved using a commercial software package and a method for solution of systems of first-order linear differential equations that uses eigenvectors and eigenvalues derived from the system of equations. The result of this work is a series of tables of fractions of acute inhalation intakes for different bioassay methods, times, and compound classes for intakes for those elements listed in ICRP Publication 68. The values in these tables can be used for intake calculations, development of bioassay frequencies, and development of action levels.

We investigated these questions by way of three meter-scale blocks of rock, two sandstones, and one volcanic tuff. Each rock exhibits visual and permeability patterns that differ in geometry, intensity, and scale. Using a gas minipermeameter, hundreds to thousands of permeability values were collected on grids at centimeter-scale resolution from each block face and compared to the digital visual image of the same face. We found no significant direct correlation between the permeability measurements and any objective textural measure drawn from the corresponding digital images, despite the obvious resemblance of the permeability maps and visual images. Hypothesizing that the human eye relies on spatial correlation to synthesize information, we calculated and compared semivariograms for both the maps and the images. Semivariogram shape, anisotropy ratio, and principal axes orientation were consistent for the maps and images of each rock but different between rocks. To explore this similarity further, we compared discrete features appearing in map/image pairs, using a difference of Gaussian edge filter to segment (i.e., delineate) the spatial features. The filter consistently colocated visually sharp features, such as sedimentological bounding surfaces, in both the map and the image. Additionally, cumulative distribution functions characterizing the size, shape, and orientation of the segmented features were statistically indistinguishable between a permeability map and its corresponding visual image but statistically different between rocks. These results suggest that it may not always be possible to use visual images (photographs or scans) of outcrops to directly map permeability, even with a training set of punctual permeability data. In particular, defining such relations may be difficult where the scales of analysis and/or intensity of heterogeneity are limited (e.g., within a given facies) as is the case here. Where direct mapping is not possible, these results suggest that visual images can still be used to delineate spatial permeability patterns, especially to locate boundaries where sharp permeability contrasts occur. Other surrogate measurements of permeability, in particular the various geophysical methods, may exhibit similar behavior. Abstract Copyright Copyright 2002 by the American Geophysical Union.

We extend the RE with an experimentally observed hold-back-pile-up (HBPU) effect not captured in the standard porous-continuum RE formulation. We postulate the HBPU effect is tied to wetting front sharpness and can be mathematically formulated in a variety of ways to include hypodiffusive, hyperbolic, and mixed spatial-temporal forms involving respectively a Laplacian, a second-order derivative in time, and a Laplacian of a first-order derivative in time of the state variables. For each, we can infer an extended flux relation comprised of the Darcy-Buckingham flux plus an additional component due to the HBPU effect. Extended flux relations that are mathematically similar to each can be found in the single-phase and multiphase flow literature, however, all with very different underlying conceptualizations of the possible physics.

Recent experimental work has demonstrated that compaction can occur in tabular zones that expand with increasing applied deformation. The appearance of compaction bands and their growth has a strong influence on the measured permeability of the host rock. The rock behind the moving compaction front can be either uniformly compacted or can consist of intercalated bands of uncompacted and compacted material. These three types of compaction would have very different effects on production from reservoirs undergoing compaction. We review the status of experimental results on localized compaction and the bifurcation theory of strain localization for compaction.

The local stresses relevant to reservoir-scale processes are strongly affected by stratigraphic and structural features at that scale, and the relationship between hydrocarbon production and the mechanical behavior of the reservoir and/or overburden can be complicated and difficult to discern from field data directly. Numerical simulation provides a means to achieve critical insight into the behavior of complex geosystems and advance understanding of both the subsurface environment before drilling as well as the relationship between fluid flow and geomechanical behavior during production. This paper reviews our recent work aimed at utilizing large-scale geomechanical simulation as a reservoir management tool. We first describe the constitutive models developed specifically for two important classes of geomaterials that are implemented in the quasi-static large-deformation finite element code JAS3D that we use in our work. We then describe several field cases where we apply nonlinear finite element modeling to key problems in reservoir mechanics. The first field cases involve historical geomechanical simulations of primary and secondary recovery at the Belridge Diatomite and Lost Hills fields located in California's San Joaquin Valley. In this work, we apply nonlinear finite element modeling to investigate the causes of well casing damage experienced by the field operators and to identify mitigation strategies. Next, we describe an application that addresses potential well integrity issues associated with sub-salt and near-salt deepwater Gulf of Mexico reservoirs. In this work, we analyze hole closure behavior and quantify loading on casings for wells that penetrate thick salt formations to ensure that wells are designed to withstand salt loading over a service lifetime of 20-30 years. The field studies illustrate the difficult issues encountered in practical applications of large-scale three-dimensional nonlinear finite element geomechanical modeling and suggest areas where research advances could be beneficial. These areas include: development of solids models and finite element meshes from disparate geologic and/or numerical data, development of realistic constitutive models, robust and efficient implementation of these material models in finite element codes to achieve reasonable solution times, experimental rock mechanics data and the natural heterogeneity of geosystems, implementation of far-field (tectonic) stresses and stress initialization, and integration of geomechanical modeling results with other analysis tools.

Rates were calculated from backscattered electron (BSE) imaging of weathered porosity and are equivalent to 1.7-5% of the surface per 1000 years. Weathering is independent of glass composition but appears to increase with flow elevation at El Malpais. Measured rates represent weathering over 3000 years and are substantially lower than glass dissolution rates measured in the laboratory over much shorter time spans. Basaltic glass is a close chemical analogue to glass hosts proposed for encapsulation of high-level nuclear wastes. Radionuclide release rates predicted from the basis of in situ field rates are substantially less than those predicted from short-term laboratory experiments.

The disposal facility, 2500 feet below the land surface in sparsely inhabited rangeland east of Carlsbad, is currently disposing of transuranic waste generated by activities related to national defense. Surface-based site characterization work began in 1974, and continued in parallel with excavation and subsurface testing beginning in 1981. Federal law assigned regulatory authority for the site to the U.S. Environmental Protection Agency in 1992. The DOE submitted a compliance certification application to the EPA in 1996, the EPA issued a final certification in 1998, and waste shipments began in 1999. Many aspects of the WIPP experience are potentially relevant to the siting and possible licensing of other geologic repositories in the U.S., including Yucca Mountain. Long-term regulatory requirements for the WIPP are similar to those for Yucca Mountain, particularly in their emphasis on probabilistic analysis and the consideration of uncertainty in estimates of 10,000-year performance. Although details of site characterization must be determined by the local geology, the overall strategy toward scientific research employed at the WIPP is broadly applicable elsewhere. Early phases of site characterization emphasized understanding and reduction of uncertainty in all aspects of the system. As understanding matured, research focussed on those areas where remaining uncertainty showed the greatest impact on performance. The DOE's certification application and the EPA's subsequent certification decision explicitly acknowledge residual uncertainty in the understanding of long-term performance, and conclude that the site meets applicable standards and provides robust protection to public health and the environment. Confidence in this conclusion comes from multiple sources, including independent technical review, thorough documentation, and adherence to a formal regulatory process.

As the pore size is reduced to a few nanometers, the separation of surface acidity constants (delta pK = pK (sub 2) -pK (sub 1) ) becomes significantly narrowed, resulting in a high surface charge density on mesopore surfaces. The change in surface acidity constants can significantly affect ion sorption onto nano-scale pore surfaces. Given the fact that nano-scale pores are widely distributed in geologic media and account for over 90% of total mineral surface area, the observed effect of nano-scale pore space confinement has important implications to many fundamental geochemical issues such as the irreversibility of ion sorption/desorption, the bioavailability of subsurface contaminants, the enrichment of trace metals in ore deposits, and the kinetics of mineral dissolution.

The frequent avulsions may be related to the influx of coarser-grained sediment from large arroyos entering the Rio Grande Valley. In this instance, avulsion may be more related to channel obstruction than to straightening of a channel or due to build-up of sediment in a meander belt. A mobile high-shear stress flume was used to model the susceptibility to erosion of sediment at three sites in the channel of the Rio Grande along the U.S. Mexico border between El Paso and Ft. Quitman, Texas. At two arroyos, Alamo and Balluco, the rapid deposition of gravelly sand at the arroyo mouths created bars that were over twice as difficult to erode as the normal channel fill. Upstream of Balluco arroyo the Rio Grande was dammed and formed a pond 1.3 m above its normal elevation. Other effects were downstream widening of the channel and the formation of mid-channel and side-channel bars. This highlights a natural process that probably effects the Rio Grande along much of its length, accretion of more poorly erodable bars within the channel during low-flow years that create dams. During floods, the river may avulse because the floodplain sediments are more easily erodable than the plug at the arroyo mouth.

During the first thousand years after emplacement, a superheated rock region is predicted to form around the tunnels as a result of heat generation from the nuclear waste. In this rock region, vigorous vaporization will form a barrier that can significantly reduce the possibility of water contacting the waste packages. The performance of this barrier depends on the nature of flow in the unsaturated fractured rock. Episodic infiltration events flowing in localized preferential flow paths may penetrate far into the superheated rock to eventually reach the emplacement drifts. This differs from results obtained with spatially and temporally averaged infiltration conditions where potential penetration distances are typically underestimated. In this paper, the probability of episodic infiltration reaching waste packages during the heating phase of the repository is studied in a systematic manner. The assumed infiltration events, while generally short in duration, are large in magnitude relative to the average infiltration. A semi-analytical solution is developed to determine the complex flow processes of such infiltration events when entering the hot rock environment. The solution scheme features a time-marching algorithm that tracks the propagation of finite masses of water flowing in vertical fractures, while an analytical solution is applied to consider mass losses resulting from vaporization caused by heat conduction from the adjacent rock. The long-term evolution of thermal-hydrological conditions in the rock is considered by simulating infiltration events at several discrete times after emplacement, covering the entire time period that repository temperatures are above boiling. Results indicate that episodic infiltration may indeed allow water to infiltrate considerable distances into the hot fractured rock. However, the heat generated from the waste packages is sufficient to reduce the probability of water entering waste emplacement drifts by a significant amount.

TRU wastes contain radionuclides and hazardous materials derived from the cleanup of defense related activities. The arrival of the first shipment of waste started a clock that will run until March 2004; by which time, the US Department of Energy must provide the EPA with documentation proving WIPP worthy of recertification. EPA must then make the decision as to whether or not WIPP continues to remain in compliance with the long-term regulatory standards of Title 40 CFR, Part 191. Recertification is a congressionally mandated regulatory checkpoint, required every five-years throughout the operational life of the repository, that determines if WIPP may continue to operate. The original certification came about in response to DOE's submittal of an enormous document--the Compliance Certification Application (CCA)--to the EPA for that agency's consideration. Likewise, the "re-certification" of the repository will come about in response to the submittal of what DOE plans to be a condensed regulatory document--the Compliance Recertification Application (CRA). In the repository vicinity, nature has not behaved precisely as predicted in the CCA, and human activity (drilling, mining, etc.) in the Delaware Basin continues to change as well. All of these changes must be taken into account by the writers of the CRA, and, ultimately, by the EPA. A smooth and complete CRA construction and submittal process, followed by diligent and efficient review by the EPA, will contribute to a straightforward determination by the EPA that WIPP continues to comply with applicable laws and regulations. This presentation will introduce the audience to the WIPP project, the CRA process, and how the public may get involved in this process.

CTH is a multimaterial Eulerian hydrocode that explicitly solves conservation of mass, momentum and energy using equations-of-state capable of representing all phases of matter. It is used predominantly for solving high strain-rate problems and is widely used by the planetary impact community to help understand the cratering process on bodies throughout the solar system. The Chesapeake Bay impactor was modeled as a 3.3 km diameter spherical asteroid consisting of dunite (density 3.32 g/cc). To simplify the calculation, two-dimensional axisymmetry was used. The projectile was assumed to be travelling vertically downward at 20 km/s. The target consisted of a 300 m layer of water overlying 200 m of water-saturated tuff and a "bedrock" of granite. The Earth's atmosphere was included to an altitude of 120 km. The calculation was run forward in time to approximately 290 seconds after impact. Maximum depth of the transient cavity (approximately 15 km) occurred at about 30 seconds. Maximum radius of the transient cavity (approximately 43 km) occurred by 120 seconds. Rebound of the central cavity lead to a region of central uplift approximately 10-15 km in radius. Removal of the surface water layer by air blast and re-impact of ejected materials occurred to a radius of approximately 67 km. Material ejected from the crater was ballistically extrapolated for 6000 seconds after impact by which time all material had re-impacted the Earth's surface. Ejecta thicknesses at 150 km, 300 km and 600 km radii were 1 m, 1 cm and 1 mm respectively.

These organic molecules with hydrophilic heads and hydrophobic tails will affect crystallization of minerals in crystal shape, microstructure, and even crystal structures. Our results from both laboratory synthesized and natural magnetite in modern soil and paleosol show nano-meter scale worm-hole-like pores. These pores are directly related to self-assembling and templating of the organic molecules. Calcite "crystals" consisted of nano-pores and calcite nano-crystals can be formed when the organic molecules exit. The calcite formed may display cube-le and even flower-like shapes. According to our results, such kinds of calcite crystals do not have to be replacement products of microbes. However, they indicate presence of the organic molecule released from microbes. Unique nano-porous structures and shapes can be formed based on silica component when the organic components exit. Mineral shapes that are different from inorganically crystallized crystals can be formed in the presence of particular organic molecule. They do not have to be replacement of microbes and take the pseudomorphs of microbes. However, such kinds of microstructures and morphologies can indicate presence of microbial activity. These indicators may be used for investigation of extraterrestrial microbial activities.

Two methods that offer considerable promise are the modulus profiler and Nuclear Magnetic Resonance (NMR) relaxation times. A modulus profiler measures the indentation of a small tip into the surface of a polymer sample. The degree of indentation at a constant load can be related to the modulus of the material. NMR relaxation times of a polymer are a measure of the molecular dynamics of the backbone chain. When a polymer is swollen in a suitable solvent, the relaxation time responds to the degree of crosslinking. The experiment requires only minutes to complete and has been performed on samples as small as 0.1 mg. The response of NMR relaxation times to aging is comparable to that of classical mechanical measurements. Examples of both techniques applied to various commercial cable jacket formulations will be presented and compared to classical measurements. JF - WIRE SYSTEM AGING.

Many of our studies involve situations where oxidation dominates degradation and this paper will review several approaches developed to address such instances. We will first describe a data analysis approach based on time-temperature superposition principles that utilizes every data point generated during accelerated tests instead of a truncated set. We will then describe an ultrasensitive oxygen consumption technique that allows data to be taken under much lower temperature aging conditions that correspond to the "extrapolation range" of conventional laboratory aging experiments. This allows much more confidence in extrapolated lifetime predictions. Finally, we will briefly describe an approach for predicting residual material lifetimes that we refer to as the Wear-out approach. JF - WIRE SYSTEM AGING.

Over a 46 min period, dyed water was infiltrated from a surface pond while electrical resistance tomography (ERT) was employed to monitor the rapid invasion of the initially dry fracture network and subsequent drainage. We then excavated the rock mass to a depth of similar to 5 m, mapping the fracture network and extent of dye staining over a series of horizontal pavements located directly beneath the pond. Near the infiltration surface, flow was dominated by viscous forces, and the fracture network was fully stained. With increasing depth, flow transitioned to unsaturated conditions, and the phase structure became complicated, exhibiting evidence of fragmentation, preferential flow, fingers, irregular wetting patterns, and varied behavior at fracture intersections. ERT images demonstrate that water spanned the instrumented network rapidly on ponding and also rapidly drained after ponding was terminated. Estimates suggest that our excavation captured from similar to 15 to 1% or less of the rock volume interrogated by our infiltration slug, and thus the penetration depth from our short ponding event could have been quite large.

Our development follows that of Aavatsmark et al., but we do not operate in transformed space. The new 27-point discretization formula has been implemented in a finite-difference reservoir simulator. This stencil has many desirable properties, including collapsing into a consistent form in two dimensions. We demonstrate that there are many practical situations in which neglecting the influence of nonorthogonality and general tensors results in first-order errors in flow predictions. A rigorous implementation for this 27-point difference operator as a control-volume finite-difference method determines the upwinding of convection terms associated with multiphase computations. Results and issues associated with implementation of this operator in a conventional finite-difference reservoir simulator are discussed. As an alternative to directly solving the linear matrix associated with the 27-point stencil of the flux-continuous operator, we examine iterative methods that split the matrix into a 7-point stencil part and a remainder. The 7-point stencil part is solved by a direct or iterative method, with the remainder part updated from the previous timestep or iteration. This split operator may permit retention of the linear solver for the standard 7-point formulation while retaining nonorthogonal grid and tensor information.

Initial conditions for each remediation experiment were created by injecting DNAPL as a point source at the top of the chamber and allowing the DNAPL to migrate downward through a water-filled, heterogeneous, sand-pack designed to be evocative of a fluvial depositional environment. This migration process resulted in the DNAPL residing as a series of descending pools. Lateral advection across the chamber was used to introduce the remedial fluids. Photographs and digital image analysis illustrate interactions between the introduced fluids and the DNAPL. In the surfactant experiments, we found that DNAPL configured in a series of pools was easily mobilized. Extreme reductions in DNAPL/water interfacial tension occurred when using the Aerosol MA surfactant, resulting in mobilization into low permeability regions and thus confounding the remediation process. More modest reductions in interfacial tension occurred when using the Tween 80 surfactant resulting in modest mobilization. In this experiment, capillary forces remained sufficient to exclude DNAPL migration into low permeability regions allowing the excellent solubilizing properties of the surfactant to recover almost 90% of the DNAPL within 8.6 pore volumes. Injection of a potassium permanganate solution resulted in precipitation of MnO sub(2), a reaction product, creating a low-permeability rind surrounding the DNAPL pools. Formation of this rind hindered contact between the permanganate and the DNAPL, limiting the effectiveness of the remediation. From these experiments, we see the value of performing visualization experiments to evaluate the performance of proposed techniques for DNAPL remediation.

Accounting for its effect on induction log responses is an ongoing research problem for the well-logging community since these types of sedimentary structures have long been correlated with productive hydrocarbon reservoirs such as the Jurassic Norphlet Sandstone and Permian Rotliegendes Sandstone. Presented here is a staggered-grid finite-difference method for simulating electromagnetic (EM) induction in a fully 3-D anisotropic medium. The electrical conductivity of the formation is represented as a full 3 x 3 tensor whose elements can vary arbitrarily with position throughout the formation. To demonstrate the validity of this approach, finite-difference results are compared against analytic and quasi-analytic solutions for tractable 1-D and 3-D model geometries. As a final example, we simulate 2C-40 induction tool responses in a cross-bedded aeolian sandstone to illustrate the magnitude of the challenge faced by interpreters when electrical anisotropy is neglected.

Calcium and Mg in the bulk and at the surface have been replaced with divalent Ni, Co, Zn, Fe, Mn, and Cd. The results of these calculations indicate that in the bulk, these impurities will prefer to substitute at the Ca site rather than the Mg site. Ca excess in dolomite is most likely incorporated as basal stacking faults; this nonstoichiometry can influence the site distribution of impurities. The calculated surface segregation energies suggest that of all the impurities studied, only Cd will show a strong preference for the (1014) surface of dolomite.

Simulated snapshots and breakthrough curves show that polydisperse colloids exhibit greater spreading than monodisperse colloids. Moreover, it is demonstrated that aperture anisotropy oriented along the flow direction substantially increases colloid spreading; whereas, aperture anisotropy oriented transverse to the flow direction retards colloid movement.

Quartz shows little variation outside analytical error, but delta (super 18) O in feldspar varies over >1 per mil. In most samples, (super 18) O/ (super 16) O fractionation between quartz and feldspar is significantly less than is predicted for equilibrium at temperatures appropriate for rhyolitic magma. In the Tshirege (upper) Member of the Bandelier Tuff, isotopic fractionation between mineral pairs is close to equilibrium in the later erupted ignimbrite, but non-equilibrium in the initial Plinian deposit. These relationships are interpreted in terms of a model where most phenocrysts are derived from a highly porphyritic carapace around the magma chamber that was disrupted by eruption, thus scattering crystals throughout the magma. Carapace quartz and feldspar are initially isotopically lighter than the bulk aphyric magma, due to chemical communication with low-delta (super 18) O country rock in the meteoric/hydrothermal system surrounding the chamber. We assume that quartz and feldspar were initially in isotopic equilibrium. Diffusive re-equilibration of crystals begins when the carapace disintegrates and the minerals are immersed in the bulk magma just prior to and during eruption. Feldspar is isotopically lighter than quartz at equilibrium, but responds more rapidly than quartz to an external change, due to a higher diffusion coefficient for oxygen. Hence, immersion in the isotopically heavier bulk magma causes feldspar and quartz delta (super 18) O values to initially converge over approximately 10 (super 2) years, and then diverge over 10 (super 3) -10 (super 4) years as first feldspar, and then quartz, re-equilibrate with the new magma. Higher delta (super 18) O variability of feldspar than quartz indicates that the shorter timescale applies to the Bandelier and Cerro Toledo rhyolites. Two important implications of this interpretation are (1) that the Bandelier magmas developed in an aphyric condition, and their porphyritic character is an artifact of eruption; and (2) that a protective, mechanically rigid cognate carapace around a silicic magma chamber may limit interaction with low-delta (super 18) O hydrothermally altered crust, thus hindering the development of significant volumes of low-delta (super 18) O silicic magma.

While numerous studies have been conducted to understand adsorption of these metals to soil minerals, less is known about long-term adsorption-desorption processes. The objective of this study was to examine the influence of residence time and organic acids on the desorption of Pb (super 2+) and Cd (super 2+) from goethite. Adsorption experiments were conducted at pH 6.0 for 1 wk (short-term) and 20 wk (long-term). Lead adsorption was nearly complete after 4 h, with very little additional sorption occurring during a 20-wk period. In contrast, Cd showed a continuous slight increase in the remaining adsorption. Desorption experiments were conducted at pH 4.5 and desorption kinetics for Pb (super 2+) and Cd (super 2+) were slow compared with the sorption reaction. Trace metal removal from the goethite surface was not completely reversible during an 8-h desorption period for all of the experiments, except for short-term Cd (super 2+) in the presence of salicylate. For all experiments except long-term Pb (super 2+) desorption, the quantity of metal desorbed from goethite followed the order salicylate > NaNO (sub 3) > oxalate. It is postulated that the greater effectiveness of salicylate compared with oxalate was related to the ability of oxalate to form bridging or ternary complexes between the metal and the goethite surface. For all experiments except Pb (super 2+) sorption in the presence of oxalate a greater quantity of metal was desorbed for the short-term compared with the long-term experiment. However, these results were only statistically significant for Pb (super 2+) in the presence of salicylate. These results suggest that residence time effects observed by many researchers are much less prevalent at low pH values, and hence natural or anthropogenic reduction in soil pH may reduce the ability of the soil to naturally sequester trace metal cations over time.

Innovations in the technique include (1) the use of eigenspectral methods for cross-spectral phase estimation and for providing subsample pick lag error estimates in units of time, as opposed to dimensionless relative scaling of uncertainties; (2) adaptive, cross-coherency-based filtering; and (3) a hierarchical waveform stack correlation method for adjusting mean intercluster pick times without compromising tight intracluster relative pick estimates. To solve the systems of cross-correlation lags we apply an iterative, optimized conjugate gradient technique that minimizes an L (sub 1) -norm misfit. Our repicking technique not only provides robust similarity classification-event discrimination without making a priori assumptions regarding waveform similarity as a function of preliminary hypocenter estimates, but also facilitates high-resolution relocation of seismic sources. Although knowledgeable user input is needed initially to establish run-time parameters, significant improvement in pick consistency and waveform-based event classification may be obtained by then allowing the programs to operate automatically on the data. The process shows promise for enhancing catalog reliability while at the same time reducing analyst workload, although careful assessment of the automatic results is still important.

AN - 52092590; 2002-049510 AB - The Molina Member is a Paleogene, sand-rich interval, up to 125 meters thick, found within the otherwise mud-dominated, non-marine Wasatch Formation of west-central Colorado. Sandstone beds of the Molina Member form sheet-like units interbedded with subordinate volumes of mudstone. The sandstones contain a low-diversity assemblage of sedimentary structures that is commonly dominated by horizontal, planar laminae, and bedding is locally contorted by large-scale soft-sediment deformation. A braided fluvial model best explains the characteristics of these strata, yet the existing braided-river models do not fully account for the assemblage of sedimentary structures or the relatively high volumes (up to half of the section) of interbedded mudstones. Two modern braided rivers, Medano Creek (Colorado) and the Prairie Dog Town Fork of the Red River (Texas), have rapid, shallow flows that form horizontal, planar bedding. In both systems the presence of large volumes of easily mobilized sandy sediment, a flashy discharge regime, and a lack of reworking between flood stages lead to the development of high-energy, shallow-water bedforms and the preservation of the resulting high-energy sedimentary structures. Similar conditions and processes are suggested to have controlled deposition of the sand-dominated Molina Member, which is a depositional anomaly within the otherwise muddy Wasatch Formation. Short-term availability of readily eroded, second-cycle sandstones from a newly elevated source area to the southeast is the most likely reason for the abrupt change from a mud-dominated fluvial system to the sandy Molina system.

One treatment cell operated for more than 3 years. The treatment cells were used for passive removal of contamination from groundwater at a uranium mill tailings repository site. Zero-valent iron [Fe(0)] that had been powdered, bound with aluminosilicate and molded into plates was used as a reactive material in one treatment cell. The others used granular Fe(0) and steel wool. The treatment cells significantly reduced concentrations of As, Mn, Mo, Se, U, V and Zn in groundwater that flowed through it. Zero-valent iron [Fe(0)], magnetite (Fe (sub 3) O (sub 4) ), calcite (CaCO (sub 3) ), goethite (FeOOH) and mixtures of contaminant-bearing phases were identified in the solid fraction of one treatment cell. A reaction progress approach was used to model chemical evolution of water chemistry as it reacted with the Fe(0). Precipitation of calcite, ferrous hydroxide [Fe(OH) (sub 2) ] and ferrous sulfide (FeS) were used to simulate observed changes in major-ion aqueous chemistry. The amount of reaction progress differed for each treatment cell. Changes in contaminant concentrations were consistent with precipitation of reduced oxides (UO (sub 2) , V (sub 2) O (sub 3) ), sulfides (As (sub 2) S (sub 3) , ZnS), iron minerals (FeSe (sub 2) , FeMoO (sub 4) ) and carbonate (MnCO (sub 3) ). Formation of a free gas phase and precipitation of minerals contributed to loss of hydraulic conductivity in one treatment cell.

One such thermal storage system, a thermocline, uses a single tank containing a fluid with a thermal gradient running vertically through the tank, where hotter fluid (lower density) is at the top of the tank and colder fluid is at the base of the tank. The thermal gradient separates the two temperature potentials. A low-cost filler material provides the bulk of the thermal capacitance of the thermal storage, prevents convective mixing, and reduces the amount of fluid required. In this paper, development of a thermocline system that uses molten-nitrate salt as the heat transfer fluid is described and compared to a two-tank molten salt system. Results of isothermal and thermal cycling tests on candidate materials and salt safety tests are presented as well as results from a small pilot-scale (2.3 MWh) thermocline.

AN - 71530078; 11906143 AB - Individuals working in iodine production require bioassay to determine if intakes have occurred. This is both to determine dose received for regulatory purposes and to verify whether workplace controls limiting the spread of contamination are adequate. Thyroid monitoring is commonly used as a bioassay technique to detect isotopes of iodine. If an individual performing iodine processing does not have a thyroid gland, other means must be used to determine intake and infer dose. Data was obtained from a previously published thesis that attempted to verify a model for absorption and retention of iodine by athyrotic individuals. These data were reevaluated to determine a pseudo uptake retention function. This analysis does not attempt to identify a biokinetic model, only to describe excretion of iodine and calculate an intake. Once the pseudo uptake retention function was derived, it was combined with the standard respiratory and gastrointestinal tract models as an inhalation intake retention function. A periodic urine bioassay protocol has been designed using the intake retention function described above and a conservative dose coefficient derived using organ dose coefficients for reference man, excluding the thyroid, and the appropriate weighting factors.

In our treatment of the problem, we assume that the electrical properties of the bedding as well as the borehole and invasion zones can exhibit transverse anisotropy. The solution process uses a Krylov subspace iteration to solve the scattering equation, which is based on the modified iterative dissipate method. Internal consistency checks and comparisons with mode matching and finite-difference solutions for vertical borehole models demonstrate the accuracy of the solution. There are no known analytical solutions for induction log responses arising from deviated boreholes intersecting horizontal bed boundaries. To simulate such responses requires the numerical solution of Maxwell's equations in three dimensions along with independent tests to validate the solution approach and its accuracy. In this paper, we compare two independent 3-D frequency-domain solutions for the problem, based on finite differences and the integral equation technique. Specific examples in the quasi-static limit are studied, including a 45 degrees deviated borehole that intersects formation bed boundaries as well as cases where the bedding exhibits transverse anisotropy. All comparisons made in this paper show very good agreement and demonstrate, for the first time, verifiable induction log responses in the presence of deviated boreholes. We also show that responses arising from deviated boreholes can be significant and must be accounted for properly when interpreting induction logs.

The finite-difference code uses a staggered grid to approximate a vector equation for the electric field. The resulting linear system of equations is solved to a predetermined error level using iterative Krylov subspace methods. To accelerate the solution at low induction numbers (LINs), a new preconditioner is developed. This new preconditioner splits the electric field into curl-free and divergence-free projections, which allows for the construction of an approximate inverse operator. Test examples show up to an order of magnitude increase in speed compared to a simple Jacobi preconditioner. Comparisons with analytical and mode matching solutions demonstrate the accuracy of the algorithm.

These help to help rank alternatives, allocate resources, and certify critical transportation operations. Existing methods may not accommodate the dynamics of changing environments and personnel threats. They may not handle hard-to-quantify, disparate data, and they may be unable to realistically estimate uncertainty. In this paper we discuss a coordinated set of ongoing model-development efforts to overcome such difficulties.

Polymeric materials (plastics and rubbers) comprise a steadily increasing proportion of the municipal and industrial waste going into landfill. Development of technologies for reducing polymeric waste, which are acceptable from the environmental standpoint, and which are cost-effective, has proven to be a difficult challenge due to complexities inherent in the reuse of polymers. Establishing optimal processes for the reuse/recycling of polymeric materials thus remains a worldwide challenge as we enter the new century. Due to the ability of ionizing radiation to alter the structure and properties of bulk polymeric materials, and the fact that it is applicable to essentially all polymer types, irradiation holds promise for impacting the polymer waste problem. The three main possibilities for use of radiation in this application are: (1) enhancing the mechanical properties and performance of recovered materials or material blends, principally through crosslinking, or through surface modification of different phases being combined; (2) treatment causing or enhancing the decomposition of polymers, particularly through chain scission, leading to recovery of either low molecular weight mixtures, or powders, for use as chemical feedstocks or additives; (3) production of advanced polymeric materials designed for environmental compatibility. This paper provides an overview of the polymer recycling problem, describes the major technological obstacles to the implementation of recycling technologies, and outlines some of the approaches being taken. A review of radiation-based recycling research is then provided, followed by a discussion of future directions where irradiation may be relevant to the problems currently inhibiting the widespread recycling of polymeric materials.

AN - 71520571; 11891208 AB - Repeated exposures to the Clara cell cytotoxicant naphthalene (NA) result in target cell populations that become refractory to further injury. To determine whether tolerance occurs from specific adaptations favoring glutathione (GSH) resynthesis without broad shifts in cellular phenotype, mice were administered NA for 21 days. We found that gamma-glutamylcysteine synthetase (gamma-GCS) was induced in tolerant Clara cells by repeated exposures to NA. Treating tolerant mice with buthionine sulfoximine, a gamma-GCS inhibitor, eliminates resistance acquired by repeated exposures to NA. Broad phenotypic shifts were not present. Marker proteins of differentiation declined over the first 3 days in the development of tolerance, but returned to control levels at 14 and 21 days. Epithelial organizational structure and internal organelle composition in Clara cells from tolerant mice were similar compared to corn oil-treated controls, while subtle shifts in organelle distribution were present. We conclude that induction of gamma-GCS expression is coordinated with the development of NA tolerance, but induction of NA tolerance does not markedly alter Clara cell differentiation, epithelial organization, or organelle composition in bronchiolar epithelium.

Each system is capable of producing a different degree of the northeast-trending permeability anisotropy recognized in Spraberry reservoirs. One fracture system consists of two vertical fracture sets with an apparent conjugate geometry (striking north-northeast and east-northeast). The other system consists of evenly spaced, north-east-striking vertical fractures, nearly bisecting the acute angle of the first system. Although lithologically similar, differences in quartz-overgrowth and clay content in the layers resulted in a yield strength of the lower bed that is only half of that of the upper layer, producing different fracture systems in the two reservoirs despite their proximity. Such differences in the mechanical properties, due to variations in diagenetic and depositional histories of the strata, are probably widespread within the formation. They have the potential to cause significant vertical and lateral variation in the Spraberry fracture system across the basin. Low present-day in-situ stresses in the reservoirs allow the fractures to open, to become more conductive, and even to propagate, under very low injection pressures.

Quitman, Texas. A combination of erodability measurements, high-precision topographic mapping using GPS, and surface geophysical measurements demonstrates the utility of this method for improving our understanding of the stream and for solving environmental problems along this highly stressed environment. At the two arroyos, Alamo and Balluco, the addition of coarse material makes the channel-filling sediments more difficult to erode downstream from the arroyos. At one site, thin beds of interstratified sand and mud make the channel much more difficult to erode. Because the EM-31 conductivity device was able to map even thin muddy layers in the shallow subsurface this site illustrates the ability of these combined techniques to map areas resistant, or particularly susceptible to erosion. The critical shear stresses required to eroded channel sediments were two-times greater downstream of the arroyos. This highlights a natural process that probably effects the Rio Grande along much of its length, accretion of more poorly erodable bars within the channel during low-flow years. These changes were associated with widening of the channel and the formation of mid-channel and side-channel bars. Arroyo mouths may form avulsion nodes because of this characteristic. The rapid deposition of Rio Grande sand at the mouth of Balluco arroyo following a flood may be an example of why the Rio Grande repeatedly avulsed prior to the construction of Elephant Butte Dam.

Geologic and hydrologic studies of the Salado conducted since the mid-1970s have led to the development of a conceptual model of the hydrogeology of the formation that involves far-field (i.e. beyond the disturbance created by the repository) permeability in anhydrite layers and at least some impure halite layers. Pure halite layers and some impure halite layers may not possess an interconnected pore network adequate to provide permeability. Pore pressures are probably very close to lithostatic pressure. In the near field around an excavation, dilation, creep, and shear have created and/or enhanced permeability and decreased pore pressure. Whether flow occurs in the far field under natural gradients or only after some threshold gradient is reached is unknown. If far-field flow does occur, mean pore velocities are probably on the order of a meter per hundreds of thousands to tens of millions of years. Most hydraulic-test responses in the Salado do not appear to reflect radial flow, but instead imply subradial (e.g. intermediate between linear and radial) flow dimensions. We believe these subradial dimensions reflect channeling of flow through fracture networks, or portions of fractures, that occupy a diminishing proportion of the radially available space, or through percolation networks that are not 'saturated' (percolation terminology meaning fully interconnected). This is probably related to the directional nature of the permeability created or enhanced by excavation effects. Inferred values of permeability cannot be separated from their associated flow dimensions. Therefore, numerical models of flow and transport should include heterogeneity that is structured to provide the same flow dimensions as are observed in hydraulic tests. Modeling of the Salado Formation around the WIPP repository should also include coupling between hydraulic properties and the evolving stress field because hydraulic properties change as the stress field changes.

This paper examines the effects of cofiring biomass and coal on ash deposition under conditions representative of those found in the superheater region of pulverized-coal boilers. Experiments were conducted with blends of eight different fuels-three types of bituminous coal, sub-bituminous coal, two types of straw, switchgrass, and wood. For each fuel, reference tests of unblended fuel establish a baseline against which to compare the results from the cofiring tests. The deposition rates for the cofire blends are between the measured deposition rates of the unblended fuels. Therefore, blending straw with coal reduces the high deposition rates observed while firing unblended straw, and cofiring coal with wood results in slightly lower deposition rates than those that occur while firing unblended coal. The primary interaction between the biomass and coal during cofiring is the reaction of the sulfur from the coal with the alkali species from the biomass. This sulfation reduces the stickiness of the deposit, which substantially reduces the deposition rate of the coal-straw blends in comparison to expectations based on the performance of the unblended fuels. Sulfation also reduces the chlorine content of the deposits, potentially reducing the corrosion potential of the deposits. A scaling parameter is proposed to estimate the deposit chlorine content on the basis of the properties of the cofire blend; the ratio of fuel-S to available alkali must be in excess of 5 times the S-to-alkali stoichiometric ratio to eliminate chlorine from the deposit. The results demonstrate that cofiring can mitigate some of the fouling difficulties associated with combustion of high-fouling biofuels.

Analysis of physical processes in the convective mantle suggests that the grain size is probably very small immediately after the phase transformations at 660 km depth and is controlled by subsequent grain growth. It was proposed that the microstructural evolution of two-phase aggregates eventually reaches an asymptotic regime in which grain growth in both phases is coupled due to Zener pinning and obeys a power-law scaling relationship d varies as t (super 1/n) . We performed Monte Carlo simulations for a particular case in which grain growth is controlled by diffusion along grain boundaries (n = 4) and found a good agreement with theoretical predictions. On geological time scales the grain size of (Mg,Fe)-perovskite is controlled by Ostwald ripening of magnesiowustite and Ca-perovskite. However, the physical parameters are poorly constrained and the grain size remains highly uncertain. If the rate-limiting process is silicon diffusion, the coarsening exponent is likely to be n = 3 and the grain size is likely to be 100-1000 mu m.

Also there are natural plumes of dissolved U associated with U ore deposits. Plume lengths tend to cluster reflecting common, contaminant-specific attenuation mechanisms. Of the more common radioactive contaminants, tritium and (super 129) I move the farthest in the subsurface. Uranium plumes on average tend to be <5 km in length; (super 99) Tc plumes can exceed a kilometer in length; (super 90) Sr plumes are typically shorter than 100 to 200 m, and (super 137) Cs plumes rarely exceed 10 to 20 m in length. Macroscopic analysis of the nature and extent of radioactive contamination in soils provides a critical perspective on the potential health risk posed by specific radionuclides. Considering the areal extent of radionuclide plumes emanating from point sources also allows a very clear assessment of the general controls over radionuclide transport. It also should constitute the basis for developing effective long-term monitoring approaches.

Remediation efforts must therefore focus on means to limit their availability to target organisms (i.e., diminish their risk). Chromium and U are both redox active elements in which the hexavalent states are most susceptible to transport and biological uptake. Their reduced counterparts, Cr(III) and U(IV), have limited solubilities and bind tenaciously to soil particles. As a consequence, reactions that promote reduction of Cr and uranyl may lead to the stabilization of these hazardous elements. Here we consider the kinetics for known reduction reactions and infer operating pathways in natural environments. Additionally, experimental data for competing or complimentary side-reactions are presented. On the basis of known rates, chromate reduction will proceed via chemical reduction by either ferrous Fe or sulfide in anaerobic soils and sediments. The importance of biological factors should not, however, be over looked inasmuch as reduction of chromate in aerobic environments will probably proceed through enzymatic means, and even in anaerobic systems microbial metabolites may be responsible for the chemical pathways. For example, we demonstrate bacterially facilitated reduction of chromate by biogenically formed ferrous Fe. By contrast, uranyl reduction is likely to occur directly through bacterially mediated reactions. Reduction of uranyl by metal reducing bacteria during respiration is common; unfortunately, alternate terminal electron acceptors may therefore compete with U(VI). Amorphous and short-range order ferric hydroxides and nitrate, for example, may retard the reduction of uranyl. Nevertheless, reductive stabilization of both U and Cr appear commonplace in soils and sediments under anaerobic conditions, a desirable situation from an environmental perspective.

Speciation of the actinides is critical for assessing environmental risks and for monitoring and controlling contaminant transport. The actinides may undergo immobilization by (co)precipitation of secondary phases or by sorption onto corroded waste packages or mineral phases, but also may be transported into the environment as molecular solution species or sorbed onto colloidal particulates. We have used a variety of spectroscopic techniques to obtain information on the speciation of the light actinides (U, Np, Pu, Am) in different environments. Through some examples, we illustrate the application of conventional and advanced ultra-sensitive speciation techniques to determine the nature of U, Np, and P species in concentrated chloride solutions, in precipitates in J-13 water from the Yucca Mountain site, and at the solid-solution interface of synthetic samples, and in contaminated soil samples from the Rocky Flats Environmental Technology Site.

This chapter describes the conditions necessary for colloid-facilitated contaminant transport to exist, given that colloid transport, itself, is occurring. The focus of this chapter is on the colloid-facilitated transport of contaminants that are, at least in principle, capable of partitioning among phases (i.e., pseudocolloids vs. intrinsic colloids). The discussion in this chapter shows that the range of three-phase system (immobile, colloid, and aqueous phases) properties required to foster colloid-facilitated contaminant transport is quite narrow. Consequently, colloid-facilitated contaminant transport will occur only under relatively rare geochemical conditions.

Reliance on reactive barriers for passive treatment of hazardous wastes involves placing permeable curtains of a reactive material in the paths of a migrating contaminant plume. Flow of contaminated groundwater through the barrier and reaction of the contaminant with the active component of the barrier would cause either conversion to a less hazardous substance, or, as in the case of some radioisotopes, their removal from the groundwater through sorption-sequestration. The key is identifying reactive components that are effective for long periods of time under soil conditions. Radioisotope retention is mineral-specific, yet also depends on the geochemistry of adjacent soils and groundwaters. Soil geochemistry determines absolute amounts of contaminant uptake as well as the long-term stability of chemical barriers. This chapter considers the soil science aspects of reactive components of barriers intended to scavenge contaminant radionuclides. Typically, these are minerals and mineral-like materials, including clays and metal oxides and hydroxides. Clays, zeolites, and hydrous ferric oxide (HFO) are effective cation sorbers whose behavior is reasonably predictable in the subsurface. In many cases HFO significantly retards Np, U(VI), SeO (sub 3) (super =) (but not SeO (sub 4) (super =) ) and Pu (V and VI). Sr, Ni, and Co are typically less retarded by HFO. Clays and zeolites are effective sorbers of Sr and Cs. Apatite-group materials are effective sequestering agents for a broad range of contaminants, though the uptake mechanisms are often poorly understood. Anion retention is particularly desirable characteristic of chemical barriers, as TcO (super -) (sub 4) and I (super -) are often calculated to be primary dose components, particularly from low-level waste facilities. Anion sorption can be engineered using insoluble oxides and hydroxides, and sulfides of divalent metals such as Cu. Iron metal also is an effective sorber of TcO (super -) (sub 4) .

Among the multiple constituents of radioactive waste, the actinide elements are of major importance due to their long half-lives of hundreds to hundred thousands of years, their radiation emission, and their toxicity for human health. In order to predict the environmental risk and release rates of actinides and to design meaningful remediation strategies, it is critical to understand the geochemical reactions actinides may undergo when being transported by natural (ground-and surface) waters into the environment. The range of potential reactions in natural aquifer systems is extremely broad because of the great variety of chemically active compounds in nature and the rich chemistry actinide elements exhibit. The light actinide elements, U, Np, Pu, and americium, can exist in multiple oxidation states, III-VI, with each forming behaviorally distinct molecular species that can differ by orders of magnitude in reactivity, stability, and solubility. The conditions of the aquifer, such as pH, redox potential (Eh), complexant concentrations, and colloid concentration, determine the predominant actinide species and their transport characteristics. Actinide solubility increases with the formation of the higher soluble penta- and hexavalent actinides. The geochemical processes that are most important for the actinides' fate in the environment are precipitation, complexation of dissolved species, interactions at solution-mineral interfaces, colloid formation, and the inteactions with microorganisms. These reactions are discussed for the light actinides (U, Np, Pu, and Am) in their environmentally most relevant oxidation states III, IV, V, and VI.

Soil phases, including clays and other hydrous compounds, are typically characterized by submicron grain size, complex and multicomponent compositions, isomorphic substitutions, heterogeneous structures, large unit cells, low symmetry, site disorder, defects, lack of long-range order, variable hydration states, and complex surface speciation. It is therefore not surprising that these phases are far from the ideal state needed to provide quality and unambiguous results from standard characterization and spectroscopic methods. Fortunately, molecular modeling methods, in recent years, have matured to an extent where they can provide significant benefit to the soil scientist and geochemist in the evaluation of sorption and interactions of radionuclides with soil phases. Molecular simulation techniques provide controlled procedures to discriminate among various competing models to explain the macroscopic observations of experiment and field studies. Computer modeling allows the soil chemist to reduce the complex nature of a sorption process to several possible structural models that can be tested using several molecular modeling tools to evaluate the local geometry, binding energy, potential reactions, transition states, and even produce diffraction patterns, and vibrational and other spectra. Results of the various structural models can then be compared with each other and with the results from experimental observations to form a more detailed conceptual model of sorption. Assuming a valid and accurate molecular model, it is even possible to model the behavior of soil phases at conditions that are not achievable by experimental means or are not observable in the field. Ultimately, any success in applying molecular modeling in these research areas must rely on a thorough understanding of the theory and knowledge of the limits of each method. Furthermore, the modeler must provide suitable validation of the models through numerous tests and applications. It is important to remember that a model may be right or wrong, but it also might be irrelevant. JF - SSSA Special Publication AU - Cygan, Randall T A2 - Zhang, Peng-Chu A2 - Brady, Patrick V.

It is illustrated that the surface speciation of Component Additivity models can be different than Generalized Composite (GC) models, because of the different approaches to fitting the pH dependence of adsorption data. Collecting experimental adsorption data at more than one partial pressure of carbon dioxide was important in achieving excellent fits between U(VI) adsorption data and model simulations. Calibration of GC models across a wide pH range (4-10) with FITEQL 4.0 yields good predictions of percent U(VI) adsorbed, but appears to result in a significant overestimation of K (sub d) values in the neutral pH range. Better agreement between the model and experimental K (sub d) values was obtained by considering data across a narrower pH range (6-8.6), which is important for application of the GC modeling approach to field data. It is recommended that a modified optimization method be developed for calibration of surface complexation models with experimental K (sub d) values.

Probabilistic performance assessment (PA) models typically use a constant sorption coefficient (K (sub d) ) for each radionuclide and each hydrostratigraphic unit. Approaches have been developed that include aspects of mechanistic sorption models into PA calculations. Simplified surface complexation models are calibrated against laboratory experiments and used to calculate actinide transport parameters. In one approach, parameter distributions are calculated based on site-specific water chemistry from the Yucca Mountain vicinity. Model results are used to provide limits on K (sub d) probability distribution functions as input into PA. Under the groundwater chemical conditions observed at Yucca Mountain, calculated sorption parameters can range across many orders of magnitude. Another approach uses the simplified surface complexation model to calculate actinide sorption behavior for a wide range in geochemical parameters. Response surfaces for actinide sorption as a function of pH and pCO (sub 2) are developed. The approaches outlined in this study can be adapted readily to current PA efforts.

Soil chemical reactions are critical to both environment and human health and to successful remediation. This chapter's aim is to briefly describes the physical and chemical characteristics of the most important radioactive nuclides likely to be found in soils. The primary sources of these radionuclides include the fallout from atmospheric weapon tests, release from fuel processes facilities, nuclear material storage facilities, biomedical applications, and, of course, naturally-occurring radioactive elements. The forms and interactions of the radionuclides in soil environment are subsequently discussed.

To address this problem, a new class of preconditioners has recently been proposed which is based on a Helmholtz decomposition of the electric field in the low induction number (LIN) regime. This paper further develops that idea, and introduces a LIN preconditioner which can be applied to problems characterized by a fully generalized anisotropic medium. Included are sample calculations demonstrating a reduction by 2 orders of magnitude in the number of "quasi-minimal residual" iterates and factor of approximately 4 speedup in the solution time for one finite-difference forward calculation. We note that in some cases where we simulate the response of a horizontal multi-component induction sonde within a crossbedded formation (not presented here, for brevity), the LIN preconditioning is able to provide results which are unobtainable by standard Jacobi preconditioning JF - SEG Annual Meeting Expanded Technical Program Abstracts with Biographies AU - Weiss, Chester J AU - Newman, Gregory A AU - Anonymous Y1 - 2002 PY - 2002 DA - 2002 SP - 320 EP - 323 PB - Society of Exploration Geophysicists, Tulsa, OK VL - 72 SN - 1052-3812, 1052-3812 KW - anisotropic materials KW - numerical models KW - finite difference analysis KW - well-logging KW - statistical analysis KW - data processing KW - electrical field KW - algorithms KW - electromagnetic logging KW - electromagnetic induction KW - 20:Applied geophysics UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/51987451?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=SEG+Annual+Meeting+Expanded+Technical+Program+Abstracts+with+Biographies&rft.atitle=A+strategy+for+rapid+solutions+in+modeling+EM+induction+in+anisotropic+media&rft.au=Weiss%2C+Chester+J%3BNewman%2C+Gregory+A%3BAnonymous&rft.aulast=Weiss&rft.aufirst=Chester&rft.date=2002-01-01&rft.volume=72&rft.issue=&rft.spage=320&rft.isbn=&rft.btitle=&rft.title=SEG+Annual+Meeting+Expanded+Technical+Program+Abstracts+with+Biographies&rft.issn=10523812&rft_id=info:doi/ L2 - http://www.seg.org/ LA - English DB - GeoRef N1 - Conference title - Society of Exploration Geophysicists, 72nd annual meeting N1 - Copyright - GeoRef, Copyright 2012, American Geosciences Institute.

The numerical model was based on the groundwater flow and transport codes MODFLOW and MT3D modified to account for electrically induced ion transport. The 6-month field demonstration was conducted in an unsaturated layered soil profile where the soil moisture content ranged from 4% to 28% (m (super 3) m (super -3) ). Specially designed ceramic-cased electrodes maintained a steady-state moisture content and electric potential field between the electrodes during the field demonstration. Acetate, a byproduct of acetic acid neutralization of the cathode electrolysis reaction, was transported from the cathode to the anode by electromigration. Field demonstration results indicated preferential transport of acetate through soil layers exhibiting higher moisture content/electrical conductivity. These field transport results agree with theoretical predictions that electromigration velocity is proportional to a power function of the effective moisture content. A numerical model using a homogeneous moisture content/electrical conductivity domain did not adequately predict the acetate field results. Numerical model predictions using a three-layer electrical conductivity/moisture content profile agreed qualitatively with the observed acetate distribution. These results suggest that field heterogeneities must be incorporated into electrokinetic models to predict ion transport at the field-scale.

This model assumed the electric potential field was constant with respect to time, an assumption valid for highly buffered soil, or when the electrode electrolysis reactions are neutralized. The model also assumed constant moisture contents and temperature with respect to time, and that electroosmotic and hydraulic transport of water through the soil was negligible. A functional relationship between ionic mobility and the electrolyte concentration was estimated using the chemical activity coefficient. Tortuosity was calculated from a mathematical relationship fitted to the electrical conductivity of the bulk pore water and soil moisture data. The functional relationship between ionic mobility, pore-water concentration, and tortuosity as a function of moisture content allowed the model to predict ion transport in heterogeneous unsaturated soils. The model was tested against laboratory measurements assessing anionic electromigration as a function of moisture content. In the test cell, a strip of soil was spiked with red dye No 40 and monitored for a 24-h period while a 10-mA current was maintained between the electrodes. Electromigration velocities predicted by the electromigration transport model were in agreement with laboratory experimental results. Both laboratory-measured and model-predicted dye migration results indicated a maximum transport velocity at moisture contents less than saturation due to competing effects between current density and tortuosity as moisture content decreases.

The ultimate goal is to aid in the development of geographically diverse geothermal resources and increase electrical power generation from geothermal resources in the continental United States. The project was initiated in April 2000 with a solicitation for industry participation in the project, and this solicitation resulted in seven successful awards in four different states. Projects consist of up to three phases, including (1) exploration and site selection, (2) drilling of a test well, and (3) testing and assessment. The seven ongoing projects are located at Rye Patch, NV, Blue Mountain, NV, Cove Fort/Sulphurdale, UT, Fourmile Hill, CA, Steamboat Springs, NV, Steamboat Hills, NV, and Lightning Dock, NM. By providing cost-shared funding of exploration and initial drilling, the DOE is attempting to mitigate the risk of initial project development in order to encourage the accessing of new geothermal resources. Results to date have been generally successful and several projects have progressed through phase II drilling activities into final assessment. In addition, a solicitation for a second round of projects (GRED II) was initiated in April 2002.

Since then, two flank core holes and a pilot hole, with a total length of 2.5 km, were drilled successfully. Borehole temperatures were measured using existing Sandia CTDL (Core Tube Data Logger) while coring. The conduit hole, with a very high angle and with about a 1700 m-drilled length, is planned to be drilled beginning in January 2003. To identify conduit position and to assure drilling safety, temperature measurements are planned during conduit drilling operations. New memory tools, with 250 degrees C temperature rating, and possibly 500 degrees C with dewar, are planned to be designed and fabricated to satisfy the project requirements.

This study, which involved the production and laboratory testing of different nonstandard cutter lots, evaluated the influence of variations in selected design and processing parameters on cutter loads, wear, and durability in hard-rock environments. The focus was on drag-bit cutters that incorporated ultrahard PDC (Polycrystalline Diamond Compact) overlays (i.e., diamond tables) on tungsten carbide substrates. Parameter variations selected for the test cutters included changes in cutter geometry, material composition, and processing conditions. Geometric variables were the diamond-table thickness, the chamfer design for the cutter edge, and the diamond-table/substrate interface configuration. Material and processing variables for the diamond table were, respectively, the nominal diamond particle size and the pressure that was applied during cutter production. Complementary drop-impact, granite-log abrasion, linear cutting-force, and rotary drilling tests examined the response of cutters from each lot. A wide range of behavior was observed from lot to lot, and analyses of the test results assessed the relative merits of these lots, allowing identification of features contributing to improved cutter performance in hard-rock (e.g., geothermal) drilling applications.

High temperature (HT) semiconductor technology has reached the point of operating at these temperatures. However, making this technology commercially viable is more difficult. Boeing's decision to utilize high temperature electronics on aircraft engines initiated the development of commercial high temperature electronics. Over the past four years, Sandia has been working to ensure that newly initiated high temperature electronic product lines meet the requirements of the geothermal industry. The development of high temperature electronics and sensors can facilitate the advancement of all aspects of geothermal power production-from futuristic power plant controls, which can look down into production and re-injection wells for control data, to drilling and logging tools with an indefinite life inside the well. Two of the shortcomings that prevented the development of a practical downhole logging tool were the lack of SOI (silicon-on-insulator) devices that would interface to large memory and a bootstrap program that would ease the implementation of user developed software. Sandia has subsequently designed and built a device to solve both of these issues, enabling a high temperature Dewarless (non-flasked) tool to become a reality. Advancements in sensors and batteries also aided in our ability to design a viable Dewarless tool.

Logistic regression, which is appropriate for binary data (indicators) analysis, is used to derive the trend component in simple kriging with varying local means (SKlm). The technique is illustrated using two types of information: 1) hard indicators sampled along transects on a hypothetical UXO site generated using a doubly stochastic Poisson process, 2) exhaustive soft information obtained through the processing of a series of realizations generated by the same point process. After risks are mapped, pixels are flagged for further investigation if the estimated probability exceeds a given threshold. This classification is used to compare the performance of the proposed technique with traditional cokriging (collocated cokriging). Fewer misclassifications and smaller false positive rates are obtained for SKlm derived from logistic regression. The proportion of false negative is below 5% for both techniques.

The system employs an array of polymer-based microsensors (chemiresistors) packaged in a waterproof housing that is designed to protect the sensor from harsh subsurface environments, including completely water-saturated conditions. The sensors and packaging have been tested in field and laboratory environments, and characterization methods are being developed that utilize contaminant-transport models and time-dependent in-situ sensor data to identify the location of the contaminant source.

The plume is usually specified by selecting a windspeed and atmospheric stability condition (Pasquill category) as input to a plume dispersion calculation for a specific, hypothetical accident. Because transport accident sites and associated atmospheric conditions are unknown until a real accident occurs, a plume model based on 'average US weather' has been made available in the RADTRAN code. Since this model does not maximise accident-risk values, critics have complained that this model is not adequately conservative. This paper presents an investigation of the accident risks, calculated with wind speeds and Pasquill categories determined for specific locations and times, along two hypothetical transport routes. Shipments at four seasons of the year and six departure times were evaluated and the risks at hypothetical accident sites, for which meteorological and solar radiation data were available to compute Pasquill categories, were summed for each route and shipment time. These sums are compared to sums of risks calculated for each of the same sites using 'average U.S. weather'. It is concluded that use of average US weather data to calculate plume dispersion yields adequately conservative results, i.e. the calculated risks bound those calculated with the time- and date-specific weather conditions.

The complex current paths are displayed using three-dimensional visualization techniques in order to better develop a qualitative understanding of the physics involved. The results indicate that electromagnetic induction in a moderately anisotropic formation is characterized by eddy current paths with significant components not only parallel, but also perpendicular, to bedding planes whenever the source magnetic dipole has a significant horizontal component. The associated magnetic fields have a strong component in the direction perpendicular to the bedding planes--a finding that supports the utility of induction sondes that include transversedipole transmitters and receivers to determine formation anisotropy and therefore minimize uncertainty in estimates of hydrocarbon potential.

Each of these fundamental processes is controlled by fracture-aperture variability and entrapped-NAPL geometry. We develop a depth-averaged computational model of dissolution that incorporates the fundamental processes that control dissolution at spatial resolutions that include all scales of variability within the flow field. Thus this model does not require empirical descriptions of local mass transfer rates. Furthermore, the depth-averaged approach allows us to simulate dissolution at scales that are larger than the scale of the largest entrapped NAPL blobs. We compare simulation results with an experiment in which we dissolved residual entrapped trichloroethylene (TCE) from a 15.4 X 30.3 cm, analog, variable-aperture fracture. We measured both fracture aperture and the TCE distribution within the fracture at high spatial resolution using light transmission techniques. Digital images acquired over the duration of the experiment recorded the evolution of the TCE distribution within the fracture and are directly compared with the results of a computational simulation. The evolution with time of the distribution of the entrapped TCE and the total TCE saturation are both predicted well by the dissolution model. These results suggest that detailed parametric studies, employing the depth-averaged dissolution model, can be used to develop a comprehensive understanding of NAPL dissolution in terms of parameters characterizing aperture variability, phase structure, and hydrodynamic conditions.

In this communication, we will present our Transmission Electron Microscopy (TEM) study on the formation of petrified woods--another example of supramolecular templating process in nature, in which inorganic silica mineral precipitation is templated by dead wood tissues (i.e., cellulose molecules). During petrification, silica minerals gradually replace wood tissues; cellular textures of tissues are commonly preserved even when the wood is completely silicified. The entire process involves silicate mineral dissolution in percolating groundwater and the subsequent precipitation of silica minerals within wood tissues. The TEM study was conducted on a petrified wood sample collected from a late Tertiary (5-20 million years ago) siliceous geologic formation in eastern Texas. Our TEM observations reveal that the sample is made of nano-scale silica particles and textural details of original wood tissues are well preserved as variations in the orientation and bulk density of silica nano-crystals. The preserved textures, including cell membranes and nucleus, range from nanometer to sub-micrometers in scale. The preservation of detailed cellular textures suggests that silica precipitation during petrification was templated by organic molecules. Based on a geochemical consideration, this templating process probably took place under alkaline to neutral pH conditions. A mechanistic understanding of the templating process based on the interaction of dissolved silica species with functional groups of tissues will be presented, and its implication to the synthesis of mesoporous silica materials will be also discussed.

Globs of silica gel must form instantaneously as a hot basalt flowing on the ground traps water puddles: the water goes supercritical, reacts with silica chains in the melt, and forms silanol-ended silica polymer chains that attach at T junctions--a gel. (If gel blobs form by puddle trapping, agates should occur near the bottom of the basalt flow. Agates do occur only in the bottom 3 meters of a 14-meter-thick basalt flow/agate quarry in the Parana Basalt at Rio Jacui, NW of Porto Alegre, Brazil, whereas the basalt vesicles, which occur only in the top meter, are all empty.) Each glob of silica gel, as a closed system, quickly crystallizes into an agate upon cooling, as the surrounding basalt crystallizes too, at high temperature. The last quartz (often coarse amethyst) to grow inside the agate may contain coprecipitated fibrous goethite: The measured lack of 18-Oxygen fractionation between the amethyst and the goethite indicates that the crystallization of both is at several hundred degrees C. The water of the initial gel glob collects in the agate's central void, itself resulting from the density difference between gel and quartz. The water leaks or flashes out and isotopically alters a shell of basalt around the agate. In a sample of fresh Deccan basalt + agate we measure delta 18-Oxygen values of 22 per mil at the edge of the agate, 15 per mil in basalt at 2 mm from the agate, 10 per mil at 1 cm, and 6 per mil at 2 cm from the agate--that is, down to fresh basalt. The same 1995 theoretical quantitative model that accounts for the self-organizational textures and compositions of agates and for their fibrous, length-fast quartz also accounts for a score of geochemical, mineralogical, microstructural, isotopic, and chromatic features of agates.

However, pore-scale heterogeneities provide a great deal of uncertainty regarding the steady vs. episodic nature of the actual flow processes. In this study, heterogeneous fracture asperities were investigated as a possible means of inducing episodic percolation events, even under steady-infiltration boundary conditions. The existence of a "pinch-point" aperture in a larger "storage" aperture was shown to create a capillary barrier capable of producing episodic accumulation and drainage events within the fracture. An episodicity factor was derived that represents the fraction of time in which flow actually drains through the fracture. The drainage event, while generally short in duration, was large in magnitude relative to the infiltration boundary condition. Results from an application of this model to the potential repository at Yucca Mountain indicated that the distribution of site-derived fracture apertures can yield a large range of episodicity factors (spanning several orders of magnitude), which resulted in considerable variability in the magnitude and frequency of the simulated percolation events. These simulated pulses of percolation were then used in analytical solutions to determine the amount of water that could penetrate into a superheated region surrounding the simulated repository drifts. This work was supported by the Yucca Mountain Site Characterization Office as part of the Civilian Radioactive Waste Management Program, which is managed by the U.S. Department of Energy, Yucca Mountain Site Characterization Project.

Here, we summarize and abstract current understanding of gravity-driven instability during infiltration into a dry, or partially saturated fracture. Recent literature, analogies taken from publications in other fields (petroleum, soil, thin film), and unpublished experiments that we have performed over the past several years are employed to help identify research needs, and the potential impact of unstable flow on predictive modeling. We then discuss the importance of specific research needs. We begin at the single fracture scale by considering gravity-driven instability with respect to: aperture heterogeneity, film flow, surface chemistry, precipitation/dissolution, and initial moisture content. We then conclude by considering phenomena that will influence unstable flows at the network scale, specifically, behavior at fracture intersections and matrix imbibition.

We designed a meter-scale laboratory experiment to explore how local processes (single-fracture and single-fracture-matrix) interact at the network scale. A thin, uncemented wall of porous bricks was constructed within a two-dimensional load frame. In a first experiment, water, chemically equilibrated with the bricks, was supplied to a fracture in the middle of the top of the initially dry system, and subsequent system behavior was followed photographically over a 71 day period. Processes acting within the fracture network placed a strong control on the temporal development of flow pathways, demonstrating the schizophrenic roles of fractures as both flow conductors and capillary barriers. Pathways formed primarily within the fractures, with minimal lateral matrix interaction across surrounding non-flowing fractures. Multiple pathways were also found to form over time. Finally, evaporation and the associated chemical precipitation led to a constraining of the flow field, where some pathways were strengthened and others starved of fluid. A second more sophisticated experiment minimized the influence of external perturbations, principally evaporation, and included sensor arrays to measure pressure, temperature, and individual fracture outflow. During wetting, the system once again showed the critical influence of fractures. Over time, the wetted structure widened with depth, as might be simulated using standard single or dual permeability models; however, fracture outflow showed erratic temporal behavior throughout the course of the 15 month experiment. These results suggest flow processes within the fracture-matrix network, along with feedback from very small external forcing, to generate a time-local "unpredictable" behavior that is not simply random. Instead, analysis of the outflow time series shows similarities with that found in systems where self organized criticality induces a response that has been defined mathematically as "complex". Taken in their entirety, the results from these experiments suggest unsaturated flow through fractured rock can exhibit behavior at all temporal scales, and that such behavior is intrinsically unstable to perturbations.

Peclet number (Pe) varied from 3 to 400, and Reynolds number (Re) varied from 0.5 to 100. In both planar- and rough-walled intersections, the mixing ratio (M (sub r) ) decreases with increasing Pe, though the decrease is less dramatic for the rough-walled geometry. In planar-walled intersections, the M (sub r) decreases with increasing Re; however, the fluted and rough-walled intersections show the opposite trend. Overall, the impact of inertial effects is slight for Re or = 1.

A. ferrooxidans derive metabolic energy from oxidation of Fe (super 2+) present in natural acid solutions and also may be able to utilize Fe (super 2+) released by dissolution of silicate minerals during acid neutralization reactions. Natural and synthetic fayalites were reacted in solutions with initial pH values of 2.0, 3.0 and 4.0 in the presence of A. ferrooxidans and in abiotic solutions in order to determine whether these chemolithotrophic bacteria can be sustained by acid-promoted fayalite dissolution and to measure the impact of their metabolism on acid neutralization rates. The production of almost the maximum Fe (super 3+) from the available Fe in solution in microbial experiments (compared to no production of Fe (super 3+) in abiotic controls) confirms A. ferrooxidans metabolism. Furthermore, cell division was detected and the total cell numbers increased over the duration of experiments. Thus, over the pH range 2-4, fayalite dissolution can sustain growth of A. ferrooxidans. However, ferric iron released by A. ferrooxidans metabolism dramatically inhibited dissolution rates by 50-98% compared to the abiotic controls. Two sets of abiotic experiments were conducted to determine why microbial iron oxidation suppressed fayalite dissolution. Firstly, fayalite was dissolved at pH 2 in fully oxygenated and anoxic solutions. No significant difference was observed between rates in these experiments, as expected, due to extremely slow inorganic ferrous iron oxidation rates at pH 2. Experiments were also carried out to determine the effects of the concentrations of Fe (super 2+) , Mg (super 2+) and Fe (super 3+) on fayalite dissolution. Neither Fe (super 2+) nor Mg (super 2+) had an effect on the dissolution reaction. However, Fe (super 3+) , in the solution, inhibited both silica and iron release in the control, very similar to the biologically mediated fayalite dissolution reaction. Because ferric iron produced in microbial experiments was partitioned into nanocrystalline goethite (with very low Si) that was loosely associated with fayalite surfaces or coated the A. ferrooxidans cells, the decreased rates of accumulation of Fe and Si in solution cannot be attributed to diffusion inhibition by goethite or to precipitation of Fe-Si-rich minerals. The magnitude of the effect of Fe (super 3+) addition (or enzymatic iron oxidation) on fayalite dissolution rates, especially at low extents of fayalite reaction, is most consistent with suppression of dissolution by interaction between Fe (super 3+) and surface sites. These results suggest that microorganisms can significantly reduce the rate at which silicate hydrolysis reactions can neutralize acidic solutions in the environment.

A high-resolution, full-field, light transmission technique was used to study the development of the instability that resulted from layering a lighter sucrose solution over a denser salt solution. The buoyancy ratio (R (sub rho ) ), which is a ratio of fluid density contributions by the two solutes and defines the degree of system disequilibrium, was varied systematically from conditions that were nearly stable (R (sub rho ) = 2.8) to those that were moderately unstable (R (sub rho ) = 1.4). In all experiments, fingers are found to form continuously throughout time from a finger "generation" zone that straddles the location of the initial interface between solutions. At low R (sub rho ) , fingers develop rapidly, merge with adjacent fingers, and grow far beyond the finger generation zone through a series of finger "conduits." In the higher R (sub rho ) experiments, fingers are slower to evolve, do not interact as dynamically, and do not grow far beyond the generation zone. Solute mass fluxes at low R (sub rho ) quickly reach a constant many times greater than that of a purely diffusive system; at high R (sub rho ) , mass fluxes decay as t (super -1/2) and behave diffusively but with effective diffusion coefficients much greater than those for molecular diffusion.

The numerical simulation of the Snorre field waterflood shows that crosswell EM field measurements provide high sensitivity to changes in the reservoir over time. This sensitivity is achieved by combining the reservoir geometry derived from surface 3-D seismic interpretation, reservoir conductivities at well locations, and constrained EM inversion of the reservoir's electrical conductivity. Inversions of 2-D and 3-D numerical models show that the changes in electrical conductivity attributable to changes in water saturation can be quantitatively mapped as a function of time. The inversions provide smooth estimates of the spatial variation of reservoir electrical conductivity that can discriminate between the level of water saturation at different stages of the waterflood. Inversions performed on 2-D data show that for the Snorre example, 3%-5% Gaussian random noise (depending on the model) can be added without a significant degradation in the inverse models. Two-dimensional inversions of the full 3-D data in the Snorre example can map the vertical average electrical conductivity within the reservoir in the interwell region almost as well as when the model is two dimensional (constant in strike direction). The effect of 3-D structure does not seriously degrade 2-D inversion in the Snorre example--even between wells that lie in a line parallel to structure. A series of 2-D inversions where various constraints and starting models are used demonstrates the importance of incorporating a priori information in the form of starting models and restricting the inversion domain to the reservoir zone. These tests show that totally unconstrained, smooth inversions of the interwell volume provide very limited quantitative information. However, when the reservoir geometry is constrained by seismic data and starting models are provided by linear interpolation of conductivities at well locations, the reservoir's vertical average electrical conductivity can be predicted to within a few percent by 2-D inversion. The Snorre field consists of a full-scale reservoir with interwell spacings that exceed 1 km where previous work has demonstrated the applicability of crosswell EM in shallow reservoirs with well separations on the order of 100 m. The simulations show that, given current transmitter and receiver technology, the magnetic fields could be measured in the Snorre field in steel-cased wells separated from the transmitter by up to 725 m.

As published in a number of recent papers, finger-like solutions with nonmonotonic profiles can be simulated numerically using a downwind averaging method. However, we find these fingers to be artifacts, generated by the combined effects of a truncation error induced oscillation or oversaturation at the wetting front, and capillary hysteresis. As the oscillation is removed, either through grid refinement or the use of inherently monotone schemes, the numerically generated fingers disappear, and the solution becomes monotonic. Thus the RE along with standard monotonic hydraulic properties does not contain the critical physics required to model gravity-driven fingers and must be considered inadequate for unsaturated flow in initially dry, highly nonlinear, and hysteretic media where these fingers occur.

Roots were collected from uninfected and infected spruce seedlings at biweekly intervals, fixed in formaldehyde-glacial acetic acid-50% ethanol (1: 1: 18), embedded in paraffin, sectioned, and tested by indirect immunofluorescence (IF). ToMV was detected by IF in infected, but not in uninfected red spruce roots. All seedlings that tested positive by IF had previously tested positive by enzyme-linked immunosorbent assay. Fluorescence was observed most frequently 2 weeks after inoculation in cortical and epidermal cells, as well as in the lateral root primordia. The ToMV was not observed in vascular tissue, the root cap, or meristematic cells. Virus distribution was uneven, and occurred in localized, concatenated pockets, parallel to the axis of the apical meristem. In older seedlings, fluorescence was associated with irregular-shaped vesicles in cortical cells.

Often a Radiation Protection Program must be developed and implemented for difficult situations. A defense in depth approach to radiation protection was developed for super(125)I production activities. Defense in depth relies on key radiation protection elements that tend to be mutually supportive and in combination provide reasonable assurance that the overall desired level of protection has been provided. For difficult situations, defense in depth can provide both a reasonable and appropriate approach to radiation protection.

The differential form of the mass conservation equation is integrated to yield an analytical expression relating elevation to a function of capillary pressure and relative permeability of the fracture and rock matrix. Constitutive relationships for unsaturated flow in this analysis are taken from van Genuchten [1980] and Mualem [1976], but alternative relations can also be implemented in the integral solution. Expressions are presented for the liquid saturations and pore velocities in the fracture, matrix, and effective continuum materials as a function of capillary pressure and elevation. Results of the analytical solution are applied to examples of infiltration in fractured rock consisting of both homogeneous and composite (layered) domains. The analytical results are also compared to numerical simulations to demonstrate the use of the analytical solution as a benchmarking tool to address computational issues such as grid refinement.

The solution is based on a weak formulation of the governing Maxwell equations using Coulomb-gauged EM potentials. The resulting sparse system of linear algebraic equations is solved efficiently using the quasi-minimal residual method with simple Jacobi scaling as a preconditioner. The main aspects of this work include the implementation of a 3-D cylindrical mesh generator with high-quality local mesh refinement and a formulation in terms of secondary EM potentials that eliminates singularities introduced by the source. These new aspects provide quantitative induction-log interpretation for petroleum exploration applications. Examples are given for 1-D, 2-D, and 3-D problems, and favorable comparisons are presented against other, previously published multidimensional EM induction codes. The method is general and can also be adapted for controlled-source EM modeling in mining, groundwater, and environmental geophysics in addition to fundamental studies of EM induction in heterogeneous media.

Intensity differences were observed when X-ray powder data from the newly synthesized compound were compared to the published powder diffraction card (PDF) 29-1015 for palmierite. Investigation of these differences indicated the possibility of preferred orientation and/or chemical inhomogeneity affecting intensities, particularly those of the basal (00l) reflections. Annealing of the palmierite was found to reduce the effects of preferred orientation. Electron microprobe analysis confirmed K:Pb:S as 2:1:2 for the for the annealed palmierite powder. Subsequent least-squares refinement and Rietveld analysis of the annealed powder showed peak intensities very close to that of a calculated palmierite pattern (based on single crystal data), yet substantially higher than many of the PDF 29-1015 published intensities. Further investigation of peak intensity variation via calculated patterns suggested that the intensity discrepancies between the annealed sample and those found in PDF 29-1015 were potentially due to chemical variation in the K (sub 2) Pb(SO (sub 4) ) (sub 2) composition.

However, it is likely that fracturing occurs in a continuum with other semi-ductile structures as flat-lying rocks are incorporated into a fold-and-thrust belt. Correctly interpreting the multiple generations of fractures and other penetrative structures can yield important clues to the sequence and conditions of deformation. The complex history of deformation and related fracturing in detachment-folded carbonate rocks of the northeastern Brooks Range illustrates this point. Regional extension fractures probably formed parallel to maximum horizontal in situ stress in relatively undeformed rocks ahead of and orthogonal to the fold-and-thrust belt. These early strike-normal fractures formed as a brittle response to layer-parallel shortening under relatively low temperature, low differential stress, and high pore fluid pressure. Subsequent deeper burial of these fractured strata and advance of the deformation front increased differential stress, temperature and strain rate. Layer-parallel shortening under these conditions probably was accommodated by semi-ductile processes. Subsequent detachment folding of the layered rocks was initially dominated by flexural slip, with associated strike-parallel and/or strike-perpendicular shear and extension fractures. Ductile processes became increasingly important as folds tightened. With waning folding and/or uplift, temperature, strain rate and differential stress decreased and the rocks once more deformed brittlely with formation of late strike-normal extension fractures. This general deformational sequence suggests that extension fractures with similar orientations but due to different stress regimes may form at different times during the evolution of a fold-and thrust belt. This may explain apparent conflicting relative ages of extension fractures in these settings.

In order of development, these pairs are oriented to form each of the three principal conjugate attitudes: upright, plan-view, and recumbent X's. One possible explanation for the sequential formation of such features is that the maximum compressive stress orientation changed with time due to changes in the local structural history. However, the axes of the different "X" geometries are parallel, suggesting that the sets are genetically related. We propose that a simpler stress history, with the horizontal stresses striking northeast and southeast and varying in magnitude but not in orientation, would also plausibly explain this sequential development. In this model, the upright X's formed under initial conditions where the overburden was the maximum and the northeast-striking horizontal stress the intermediate stress. Plan-view X's formed next as the northeast-striking stress increased (due to northeastward Laramide translation of the Colorado Plateau and interaction with the local basement-cored uplift) to become the maximum stress, leaving the overburden stress as the intermediate stress although unchanged in magnitude. As the northeast-directed horizontal stress continued to increase it created conditions where both horizontal stresses exceeded the overburden, resulting in incipient thrust faulting of the recumbent X's. Mechanically, it can be shown that stress levels dropped temporarily once they reached failure at each stage, interrupting deformation so that no overlap occurred. The three sets of intersecting conjugate deformation bands resulted in extremely compartmentalized potential reservoirs.

The main goals of our DOE/NETL project are to better understand, predict and monitor the migration and ultimate fate of injected CO2 in an oil reservoir through a field demonstration experiment at a site in southeastern New Mexico. Advanced modeling and flow simulation techniques were used to develop a geologic model of the site and to verify the feasibility of CO2 injection into that reservoir. The results of these simulations will be used to decide on wellhead injection conditions, to guide selection of geophysical survey parameters and to bound test conditions for lab experiments using core samples. A suite of modern geophysical characterization techniques will be used to monitor the advancing CO2 plume both during and after injection. The field data will provide a unique opportunity to test, refine and calibrate the computer model(s) that simulate those subsurface interactions. The laboratory experiments will measure changes in reservoir formation properties and chemical reactions with CO2 flooding. Iteration of modeling, laboratory and field data will improve simulation tools and provide higher quality input data for those models. Ultimately, these results will be used to predict storage capacity and physical and chemical changes in reservoir properties, such as fluid composition, porosity, permeability, and phase relations. Science or technology gaps related to engineering aspects of CO2 sequestration would be identified in the course of this study.

The changes in the macrocycle vibrational modes are consistent with a Ca super(2+)-dependent increase in the out-of-plane distortion of the low-potential heme, the proposed peroxidatic heme. Most of the increase in out-of-plane distortion occurs when the high-affinity site I is occupied, but a small further increase in distortion occurs when site II is also occupied by Ca super(2+) or Mg super(2+). This increase in the heme distortion explains the red shift in the Soret absorption band that occurs upon Ca super(2+) binding. Changes also occur in the low-frequency substituent modes of the heme, indicating that a structural change in the covalently attached fingerprint pentapeptide of the LP heme occurs upon Ca super(2+) binding to site I. These structural changes may lead to loss of the sixth ligand at the peroxidatic heme in the semireduced form of the enzyme and activation.

In this paper, we have developed a linear free energy correlation model that correlates metal partition coefficients with metal cation properties: -2.303 RT logK (sub d) + Delta G(SUPER 0) (sub f,M(SUPER Z+)) = a(SUPER *) (sub M(SUB H)X) Delta G(SUPER 0) (sub n,M(SUPER Z+)) + beta (SUPER *) (sub M(SUB H)X) r (sub M(SUPER Z+)) +b(SUPER *) (sub M(SUB H)X) where a(SUPER *) (sub M(SUB H)X) , beta (SUPER *) (sub M(SUB H)X) , and b(SUPER *) (sub M(SUB H)X) are constants, which can be determined by a regression analysis. For isovalent metal partitioning, because of the constraint of K (sub d) = 1 for the host metal, this correlation can be also expressed as: -2.303 RT log K (sub d) = a(SUPER *) (sub M(SUB H)X) (Delta G(SUPER 0) (sub n,M(SUB H)(SUPER Z+)) - Delta G(SUPER 0) (sub n,M(SUB H)(SUPER Z+)) ) + beta (SUPER *) (sub M(SUB H)X) (r (sub M(SUPER Z+)) - r (sub n,M(SUB H)(SUPER Z+)) ) - (Delta G(SUPER 0) (sub f,M(SUPER Z+)) - Delta G(SUPER 0) (sub f,M(SUB H)(SUPER Z+)) ). Host minerals from an isostructural family have the same linear free energy relationship, as long as the relationship is expressed as a function of the differences in cation properties between substituent and host metals. We have applied our model to both isovalent and non-isovalent metal partitioning in carbonate minerals. The model closely fits experimental data, demonstrating the robustness of the proposed linear free energy relationship. Using the model, we have predicted the partition coefficients of divalent and trivalent metals between various carbonate minerals and aqueous solutions. The differences between the predicted and experimental values are generally less than 1 logarithmic unit for divalent cations and less than 0.4 logarithmic unit for trivalent cations. Magnesite is predicted to have the largest partition coefficients among the carbonate minerals with a calcite structure and therefore, can be a good scavenger for toxic metals. The kinetic effect on metal partitioning can be described graphically by a "seesaw" line anchored at a host cation. To explain the rate dependence of partition coefficients, we have proposed a conceptual model that relates metal partitioning to surface adsorption. The conceptual model suggests that as the rate of host mineral precipitation increases, the ratio of substituent to host cation in a solid approaches what is in the adsorbed layer. The linear free energy correlation model developed in this paper provides a useful tool for systematizing the existing experimental data and for predicting unknown partition coefficients.

Parameter estimation is used to determine the mean and standard deviation of a lognormal distribution of diffusion rate coefficients as well as the advective porosity and longitudinal dispersivity. At two different test sites both multirate and single-rate models are capable of accurately modeling the observed data. The single-well injection-sswithdrawal test provides more precise estimates of the mass transfer parameters than the convergent flow tracer tests. Estimation of the multirate distribution parameters is consistent across locations for the two types of tests. Limits of resolution are calculated for the multirate distribution, and these limits explain the precision with which the standard deviation of the multirate distribution can be estimated. These limits also explain the necessary increase in the advective porosity for the single-rate model at one location and not the other. Implications of the multirate mass transfer model at time and length scales greater than those of the tracer tests include the instantaneous equilibrium of a significant fraction of the matrix and the possibility of a fraction of the diffusive porosity not reaching an equilibrium solute concentration at long times.

The tests were designed to evaluate transport processes, especially matrix diffusion, in fractured, permeable media. Both single-well injection-withdrawal (SWIW) and multiwell convergent flow (MWCF) tests were conducted. Seventeen different organic tracers (the fluorobenzoic and chlorobenzoic acids) and iodide were used as conservative tracers for the tests. The MWCF tests included repeated tracer injections while pumping the central well at different rates, injection of tracers with different aqueous diffusion coefficients, and injection of tracers into both the full and partial formation thickness. This paper describes the tracer test sites and aquifer characteristics, the experimental methods, and the tracer data produced. The tracer test results provide a high-quality data set for a critical evaluation of the conceptual model for transport. Both the SWIW and MWCF tracer test data showed gradual mass recovery and breakthrough (or recovery) curve tailing consistent with matrix diffusion. However, the SWIW recovery curves did not display the -1.5 log-log slope expected from a conventional double-porosity medium with a single rate of diffusion. The breakthrough curves from MWCF tests conducted at two different pumping rates showed similar peak heights, which is also not what was expected with a conventional double-porosity model. However, the peak heights were different for two tracers with different aqueous diffusion coefficients that were injected simultaneously in one test, consistent with the effects of matrix diffusion. The complexity of the tracer test results suggests that a simple double- porosity conceptual model for transport in the Culebra with a single rate of diffusion is overly simplistic.

We first investigated the ability of a conventional double-porosity model and a multirate diffusion model to explain the data. This revealed that the multirate diffusion hypothesis/model is consistent with available data and is capable of matching all of the recovery curves. Second, we studied the sensitivity of the SWIW recovery curves to the distribution of diffusion rate coefficients and other parameters. We concluded that the SWIW test is very sensitive to the distribution of rate coefficients but is relatively insensitive to other flow and transport parameters such as advective porosity and dispersivity. Third, we examined the significance of the constant double-log late time slopes (-2.1 to -2.8), which are present in several data sets. The observed late time slopes are significantly different than would be predicted by either conventional double- porosity or single-porosity models and are believed to be a distinctive feature of multirate diffusion. Fourth, we found that the estimated distributions of diffusion rate coefficients are very broad, with the distributions spanning a range of up to 3.6 orders of magnitude. Fifth, when both heterogeneity and solute drift are present, late time behavior similar to multirate mass transfer can occur. Although it is clear that multirate diffusion occurs in the Culebra, the number of orders of magnitude of variability may be overestimated because of the combined effects of drift and heterogeneity.

[2000] conducted in macroheterogeneous porous media. For experiments where viscous forces were nonnegligible, we redefine the total pore filling pressure to include viscous losses within the invading phase as well as the viscous influence to decrease randomness imposed by capillary forces at the front. NP MMIP exhibits the complex invasion order seen experimentally with characteristic alternations between periods of gravity-stabilized and destabilized invasion growth controlled by capillary barriers. The breaching of these barriers and subsequent pore-scale fingering of the nonwetting phase is represented extremely well, as is the saturation field evolution and total volume invaded.

Recent synthetic efforts to mimic such natural designs have focused on nanocomposites, prepared mainly by slow procedures like monomer or polymer infiltration of inorganic nanostructures or sequential deposition. Here we report the self-assembly of conjugated polymer/silica nanocomposite films with hexagonal, cubic or lamellar mesoscopic order using polymerizable amphiphilic diacetylene molecules as both structure-directing agents and monomers. The self-assembly procedure is rapid and incorporates the organic monomers uniformly within a highly ordered,inorganic environment. Polymerization results in polydiacetylene/silica nanocomposites that are optically transparent and mechanically robust. Compared to ordered diacetylene-containing films prepared as Langmuir monolayers or by Langmuir-Blodgett deposition, the nanostructured inorganic host alters the diacetylene polymerization behaviour, and the resulting nanocomposite exhibits unusual chromatic changes in response to thermal, mechanical and chemical stimuli. The inorganic framework serves to protect, stabilize, and orient the polymer, and to mediate its function. The nanocomposite architecture also provides sufficient mechanical integrity to enable integration into devices and microsystems.

A surveillance video camera and satellite-based records enabled computing the trajectory and orbit independently of visual sightings of casual observers. The superbolide body of about 36 000 kg penetrated the atmosphere with an initial velocity of 30.5+ or -1.7 km s (super -1) . Its orbit was a long-period orbit and seems to be at variance with the low value of ablation coefficient (0.017 kg MJ-1) derived from modeling the atmospheric trajectory. However, such an event has been documented previously. Also the intensity and brevity of the satellite-detected light flares are highly unusual. The impact area of the main hypothetical remnant of the body is given. Search for meteorites was performed. No meteorites were recovered. Also analysis of snow samples gave no hint of meteoritic dust.

The Pliocene-aged Camp Rice Formation, which consists of alluvial, fluvial, and lacustrine sediments, and paleosols, is well-exposed at Rincon Hills on the east side of the fault zone. These sediments were silicified near the fault zone by hydrothermal activity. Clay samples taken from the Camp Rice Formation in and around the hydrothermally altered zone consisted predominantly of well-ordered dioctahedral smectite. Other clays in these sediments included interstratified illite-smectite and kaolinite. In most samples, the dioctahedral smectite was montmorillonite. Iron-rich smectite (possibly nontronite) was present in thin clay-rich layers immediately above and below an opal tufa-like deposit just east of Rincon Hills.

The well-formed films and laths of dioctahedral smectites in and around the alteration zone are probably authigenic clays formed by hydrothermal solutions.

Groundwater occurs in both the regional aquifer and in a localized perched aquifer. The regional aquifer is Albuquerque's drinking water source and is at a depth of 500 to 600 ft in unconsolidated sediments of the upper unit of the Tertiary Santa Fe Group. Flow direction in the study area is north-northwest toward production wells. Groundwater travels preferentially through highly conductive sediments associated with the ancestral Rio Grande. The perched aquifer consists of multiple, saturated intervals 175 to 275 ft above the regional aquifer. This system has only been identified in the north-central portion of SNL/NM and does not appear to be hydraulically connected to the regional aquifer. Flow in this system is probably to the southeast and is likely controlled by gently dipping beds of fine-grained alluvial fan sediments. The two aquifers are geochemically distinct, with the regional aquifer exhibiting more consistent geochemistry both over time and between wells. The perched water is more geochemically variable and has concentrations of calcium, chloride and sulfate generally greater than found in the regional aquifer. Water levels in the two aquifers currently represent transient conditions possibly due to cessation of anthropogenic recharge. Over time, water levels in both the regional and perched aquifers are increasing in elevation in the southeastern portion of the study area (toward the mountain front), and are decreasing in the northwestern portion of the study area (toward water supply wells). TCE has been detected in 5 of 12 shallow-system monitoring wells. Concentrations exceed the regulatory limit of 5 mg/L at two of the five locations. Vapor-phase source(s) of TCE are currently suspected; the fine-grained alluvial sediments and lack of recharge hinder downward transport of the vapor-phase TCE.

These materials, referred to as "speleogenetic by-products," are categorized as primary or secondary. Primary speleogenetic by-products are formed directly from H (sub 2) SO (sub 4) speleogenesis by H (sub 2) S-H (sub 2) SO (sub 4) reaction with carbonate bedrock and internal sediments. They are found in cave areas protected from flood or drip waters. Secondary speleogenetic by-products are minerals and amorphous materials that formed by the alteration of the primary speleogenetic by-products, or by the late-stage remobilization of elements concentrated during speleogenesis. Primary speleogenetic by-products in these caves are gypsum, elemental sulfur, hydrated halloysite, alunite, natroalunite, jarosite, hydrobasaluminite, quartz, todorokite, rancieite, and amorphous silica and aluminum sulfates. Gypsum is the most abundant by-product, whereas alunite is the most significant because it can reveal the timing of speleogenesis. Aluminite, tyuyamunite, quartz, opal, and gypsum are secondary speleogenetic by-products. Other possible speleogenetic by-products are celestite, hydrous iron sulfates, gibbsite, nordstrandite, goethite and dolomite. The carbonate bedrocks in which the caves have formed are predominantly dolostone and limestone; mineral assemblages of these host rocks include calcite, dolomite, quartz, illite, dickite, kaolinite, interstratified illite/smectite, montmorillonite, and mica. The process of H (sub 2) SO (sub 4) speleogenesis for Carlsbad Cavern and Lechuguilla Cave, and its by-products provide a general model for similar cave and non-cave systems worldwide.

A two-dimensional micromodel and image capture system were applied to observe microscale NAPL mobilization and solubilization phenomena. In each experiment a common residual NAPL field was established, followed by a series of mobilization and solubilization experiments. Mobilization floods included pure water floods with variable flow rates and surfactant floods with variations in surfactant formulations. At relatively low capillary numbers (N (sub ca) < 10 (super -3) ) the surfactant mobilization floods resulted in higher NAPL saturations than for similar N (sub ca) pure water floods. These differences in macroscopic saturations are explained by differences in microscale mobilization processes. Sqlubilization of the residual NAPL remaining after the mobilization stage was dominated by the formation of microscale dissolution fingers, which produced nonequilibrium macroscale NAPL solubilization. A macroemulsion phase also was observed to form spontaneously and persist during the solubilization stage of the experiments. Copyright 2001 by the American Geophysical Union.

AN - 77027912; 11288584 AB - Microbial reactions play an important role in regulating pore water chemistry as well as secondary mineral distribution in many subsurface systems and, therefore, may directly impact radionuclide migration in those systems. This paper presents a general modeling approach to couple microbial metabolism, redox chemistry, and radionuclide transport in a subsurface environment. To account for the likely achievement of quasi-steady state biomass accumulations in subsurface environments, a modification to the traditional microbial growth kinetic equation is proposed. The conditions for using biogeochemical models with or without an explicit representation of biomass growth are clarified. Based on the general approach proposed in this paper, the couplings of uranium reactions with biogeochemical processes are incorporated into computer code BIORXNTRN Version 2.0. The code is then used to simulate a subsurface contaminant migration scenario, in which a water flow containing both uranium and a complexing organic ligand is recharged into an oxic carbonate aquifer. The model simulation shows that Mn and Fe oxyhydroxides may vary significantly along a flow path. The simulation also shows that uranium(VI) can be reduced and therefore immobilized in the anoxic zone created by microbial degradation.

This paper describes the development and application of LEHGC2.0, a mechanistically based numerical model for simulation of coupled fluid flow and reactive chemical transport, including both fast and slow reactions in variably saturated media. Theoretical bases and numerical implementations are summarized, and two example problems are demonstrated. The first example deals with the effect of precipitation/dissolution on fluid flow and matrix diffusion in a two-dimensional fractured media. Because of the precipitation and decreased diffusion of solute from the fracture into the matrix, retardation in the fractured medium is not as large as the case wherein interactions between chemical reactions and transport are not considered. The second example focuses on a complicated but realistic advective-dispersive-reactive transport problem. This example exemplifies the need for innovative numerical algorithms to solve problems involving stiff geochemical reactions.

Essentially permanent isolation must be demonstrated in those few settings where high nuclear level wastes contaminated the environment with (super 135) Cs (half-life 2.3X10 (super 6) years) in addition to (super 137) Cs. Clays are potentially a low-cost barrier to Cs movement, though their long-term effectiveness remains untested. To identify optimal clays for Cs retention, Cs desorption was measured for five common clays: Wyoming Montmorillonite (SWy-1), Georgia Kaolinites (KGa-1 and KGa-2), Fithian Illite (F-Ill), and K-Metabentonite (K-Mbt). Exchange sites were pre-saturated with 0.16 M CsCl for 14 days and readily exchangeable Cs was removed by a series of LiNO (sub 3) and LiCl washes. Washed clays were then placed into dialysis bags and the Cs release to the deionized water outside the bags measured. Release rates from 75 to 139 days for SWy-1, K-Mbt and F-Ill were similar; 0.017% to 0.021% sorbed Cs released per day. Both kaolinites released Cs more rapidly (0.12% to 0.05% of the sorbed Cs per day). In a second set of experiments, clays were Cs-doped for 110 days and subjected to an extreme and prolonged rinsing process. All the clays exhibited some capacity for irreversible Cs uptake. However, the residual loading was greatest on K-Mbt ( approximately 0.33 wt.% Cs). Thus, this clay would be the optimal material for constructing artificial reactive barriers.

Performance assessment (PA) analyses indicate that human intrusions by inadvertent, intermittent drilling for resources provide the only credible mechanisms for significant releases of radionuclides from the disposal system. For long-term brine releases, migration pathways through the permeable layers of rock above the Salado formation are important. Major emphasis is placed on the Culebra Member of the Rustler Formation because this is the most transmissive geologic layer overlying the WIPP site. In order to help quantify parameters for the calculated releases, radionuclide transport experiments have been carried out using intact-core columns obtained from the Culebra dolomite member of the Rustler Formation within the WIPP site. This paper deals primarily with results of analyses for super(241)Pu and super(241)Am distributions developed during transport experiments in one of these cores. Transport experiments were done using a synthetic brine that simulates Culebra brine at the core recovery location (the WIPP air-intake shaft (AIS)). Hydraulic characteristics (i.e., apparent porosity and apparent dispersion coefficient) for intact-core columns were obtained via experiments using the conservative tracer super(22)Na. Elution experiments carried out over periods of a few days with tracers super(232)U and super(239)Np indicated that these tracers were weakly retarded as indicated by delayed elution of the species. Elution experiments with tracers super(241)Pu and super(241)Am were attempted but no elution of either species has been observed to date, including experiments of many months' duration. In order to quantify retardation of the non-eluted species super(241)Pu and super(241)Am after a period of brine flow, non-destructive and destructive analyses of one intact-core column were carried out to determine distribution of these actinides in the rock. Analytical results indicate that the majority of the super(241)Am remained very near the injection surface of the core (possibly as a precipitate), and that the majority of the super(241)Pu was dispersed with a very high apparent retardation value. The super(241)Pu distribution is interpreted using a single-porosity advection-dispersion model, and an approximate retardation value is reported.

Specifically, a "matrix-free" implementation of the well-known staggered grid finite difference (FD) algorithm is derived for use with Krylov subspace methods for solving the resulting sparse system of linear equations. The method is matrix-free in that the Krylov methods require computing the action of the matrix on an arbitrary vector, but not explicit storage of the matrix itself. For example, in using the quasi-minimal residual method to solve a linear system with NDF degrees of freedom, the strorage cost is reduced from 23NDF to 10NDF complex double precision words. Benchmarking results indicate that run times for the matrix-free method are competitive with their stored-matrix counterparts. As a preliminary example of its utility, the matrix-free formulation was adapted for parallel distributed memory computation of synthetic induction logs. This work complements recent efforts toward the design of a "low induction number" preconditioner which, while reduces the overall runtime by as much as an order of magnitude for some problems, nearly doubles the storage requirements necessary for a solution to the FD system of equations.

These conductors can be pipelines, power lines, railroad tracks, fences, brine ponds, etc. In this paper, two cases are investigated through numerical simulations: a long, linear conductor parallel to one edge of a square transmitting loop, and a short, linear conductor inside and crossing the edge and outside of the square transmitting loop. These conductors are in contact with the earth over their entire length. This work focuses on the computational simulation of TEM responses for these types of conductors. The TEM responses are calculated using a 3D finite-difference timedomain electromagnetic code. Results of the 3D TEM simulations show that care must be exercised in interpreting the TEM responses in the presence of surface conductors.

AN - 911677152; 2012-006046 AB - Based on observations from two distinct settings, a faulted sandstone aquifer and a clay-rich alluvial floodplain, we present evidence that near-surface controlled-source electromagnetic (CSEM) responses are fractal signals. The observed responses are very rough; they do not show the statistical behavior of smoothly varying functions superimposed by random Gaussian noise. This suggests that CSEM signals reflects self-similarity in the underlying, heterogeneous electrical conductivity structure. The process of EM induction in the Earth thus may be regarded as a mapping from a fractal medium to a fractal response. This result poses exciting new challenges for numerical modeling and geological interpretation of CSEM responses in the areas of engineering and environmental geophysics and shallow resource development.

A novel microsensor system has been developed that can be used to monitor and characterize volatile organic contaminants in the subsurface. This system has been employed in a number of laboratory experiments in this study to evaluate diffusion of volatiles in porous media. The transient diffusion of water vapor and iso-octane vapor was monitored by the sensors in one-dimensional column experiments in air and in sand. Calibration data were used to convert sensor responses to vapor concentration, and results were plotted as a normalized concentration versus time to generate standard breakthrough curves. These were compared to theoretical predictions that were derived from the diffusion equation, with appropriate boundary conditions and parameters taken from the experimental conditions. A comparison of the experimental and theoretical results produced estimates of diffusion coefficients that were close to values reported in the literature. The results also provided an increased understanding of the behavior of the microsensors in porous media.

First, smaller events are typically more difficult to detect and locate. Second, as characterized by the Richter/Gutenberg frequency of occurrence relation, there are many more small events than large events so the monitoring workload is exponentially increased. These issues represent a new challenge for the nuclear explosion monitoring community, but for regional network operators they are commonplace and, to a large extent, solved. These operators routinely locate and identify large numbers of events at least as small as those of interest to the monitoring community, often on the basis of as little as one waveform. The operators accomplish this seemingly impossible task by simply viewing and recognizing the similar waveforms from repeating seismic sources such as mines. Such an analyst-intensive, subjective process is not generally appropriate for nuclear explosion monitoring, but the effectiveness of this technique suggests that automated pattern recognition techniques could have a significant impact on monitoring. In this paper we will show how cluster analysis (CA) techniques can be used to automate the waveform recognition problem and compare the performance of different CA methods. Cluster analysis is the term for a family of techniques for aggregating similar entities into groups or clusters. In this study we compare three different CA techniques: agglomerative hierarchical clustering (represented by dendrograms), Q-mode factor analysis, and ordination. Our data set consists of 651 regional distance events recorded by the New Mexico Institute of Technology network from July 1997 through February 1998. The events are predominantly mining explosions from operations in western New Mexico, as well as southeast Arizona. Because we have full-network recordings for these events, we are able to locate events from within each cluster to tie the clusters to known mining regions. All of the cluster techniques are based on a similarity matrix formed by comparing each entity with every other entity. For this study, we base our measure of similarity on normalized waveform correlations for a single station. The resulting clusters depend strongly on the processing parameters applied to the waveforms (phase windowing, filtering, Hilbert enveloping). Our results suggest that dendrograms of the Hilbert enveloped waveforms produce the most useful results, while factor analysis may prove useful as an auxiliary technique. Ordination produced marginally useful results only after non-linear rescaling of the similarity data, and we do not think it shows promise with this type of data. None of the CA techniques automatically determine how many clusters are represented in the data. This decision is often made subjectively, but it can be based on the application of clustering criteria. We compared several proposed clustering criteria methods to determine which work the best for our data set, but none performed well in general.

The method involves defining a set of kriging and travel-time model parameters within specific seismic provinces whose boundaries are defined by an enclosing polygon. Each polygon's boundary edges are further characterized using a set of transition blending functions that describe the reduction in influence of the polygon's statistical and model parameters as a point of interest moves from within the polygon boundary to outside the boundary. Spatial domains that are not covered by specific region-dependent polygons inherit a default set of kriging parameters and travel-time models. The entire collection of seismic provinces and the default region determine the extent of the multi-region model. Region-based statistical and model parameters are averaged at points of interest using an assigned weight based on the amount of influence exerted by each of the regions that are near the point of interest. The weights are normalized to the total influence exerted by all regions influencing the point of interest. Transitions at the vertices of the polygons are smoothed using a patching circle to ensure that the entire bounding influence transition is continuous and differentiable everywhere. With this approach, not only statistical model parameters such as kriging, correlation, shape, and range can be regionally integrated over a broad area, but so can region-dependent model parameters such as total travel time, ellipticity corrections, model variance, and bulk static corrections. In fact, any regional based parameter can be successfully deployed over the entire multi-region domain. Using this approach, a set of statistically distinct spatial regions can be combined into a single continuous interpolated surface for use by client applications that communicate with the NNSA Parametric Grid Library (PGL). Elements of the multi-region model are currently used by the NNSA Calibration Integration Tool (CIT) and the Client GNEM Interface (CGI) Library.

Regularized Discrimination Analysis (RDA) is a multivariate seismic event identification method that can be applied to a number of highly correlated regional discriminants. The parametric formulation of RDA includes Linear Discrimination (LDA), Quadratic discrimination (QDA) and Euclidean distance-based nearest-neighbor discrimination. We present methods to optimally select RDA parameters. Error propagation is another focus area in the NNSA NEM R&E program. The detection and timing of seismic arrivals play a critical role in the ability to locate seismic events, especially at low magnitude. Errors can occur with the determination of the timing of the arrivals, whether these errors are made by automated processing or by an analyst. One of the major obstacles encountered in properly estimating travel-time picking error is the lack of a clear and comprehensive discussion of all of the factors that influence phase picks. We have developed a multivariate statistical model, experimental design, and analysis strategy that can be used in this study. We have embedded a general form of the International Data Centre (IDC)/U.S. National Data Center (USNDC) phase pick measurement error model into our statistical model. We can use this statistical model to optimally calibrate a picking error model to regional data. We also present work on the development of statistical methodologies for comparing effects of station-specific correction surfaces on predicted seismic event locations and event location uncertainty from network model Monte Carlo simulation runs. Research and development work includes the investigation of Latin Hypercube Sampling (LHS) to design Monte Carlo simulation runs, the development of appropriate statistical models to describe travel-time correction surface errors, and the proper simulation of errors in phase identification and association processes. Also under investigation are statistics-based methods for visualizing and assessing differences between event locations and location uncertainty from different correction surfaces in network model simulations.

The site combines a partially saturated hydrologic system and a stratigraphy of fractured, welded, and nonwelded tuffs. The long timescale for site hydrologic phenomena limits the applicability of direct measurements. Also, mathematical modeling is difficult because the tuffs exhibit widely varying, and often highly nonlinear, hydrologic properties. To increase a basic understanding of both the hydrologic properties of tuffs and the modeling of flow in partially saturated regimes, the following tasks were performed. (1) Laboratory Experiment: water imbibition into a cylinder of tuff (taken from Yucca Mountain drill core) was measured by immersing one end of a dry sample in water and noting its weight as a function of time; the flow of water was approximately one dimensional, filling the sample from bottom to top. (2) Computer Simulation: the experiment was then modeled using TOSPAC (a one-dimensional, finite-difference computer program for simulating water flow in partially saturated, fractured, layered media) with preliminary data currently considered for use in site-scale modeling of a repository in Yucca Mountain. The measurements and the results of the modeling are compared. Conclusions are drawn with respect to the accuracy of modeling transient flow in a partially saturated, porous medium using a one-dimensional model and currently available hydrologic property data.

A standard API Slot Tester has been modified to improve the reliability of this testing and a baseline for mud and bridging material distribution was established. A recent request was made by the drilling industry for evaluation tests on lost circulation material currently being used in geothermal drilling operations in Indonesia and the Philippines. Sandia test equipment was reassembled and a series of tests were conducted. This report documents the results of evaluation tests on the new materials when they were added to standard water-based bentonite mud, containing walnut shells, and used to plug a simulated loss zone.

Yet these bits drill at slow penetration rates in hard rock due to performance limitations inherent in their operation. Conversely, polycrystalline diamond compact (PDC) bits have an aggressive cutting structure but have not found widespread use in drilling hard rock. Nevertheless, PDC bits are capable of drilling the high compressive strength, abrasive formations characteristic of many geothermal formations subject to certain limitations in their design and operating conditions. In this paper, performance data are presented from laboratory testing of representative roller cone and PDC bits in hard-rock formations that indicate today's PDC bits can drill high compressive strength rock significantly faster than hardformation roller cone bits. The advantages offered by PDC bits in hard rock are discussed along with the cost savings that can be realized relative to roller cones. The benefits from using PDC bits are contrasted with their limitations in regard to wear resistance and impact loading. Cutter wear testing confirms that the abrasion resistance of PDC cutters has improved to where drag bits are economically viable for drilling abrasive formations. Yet improper operation of PDC bits can lead to accelerated wear of the individual cutters. Improper drilling parameter selection can also lead to dynamic instability of the entire drill string, possibly resulting in cutter impact damage and failure as the severity of bit vibration increases. It is shown that PDC bit stability exists at specific rotary speed/weight on bit combinations for a given bit and drillstring configuration whereby the severity of vibration can be controlled allowing the bit to remain seated in the rock. The performance improvements available indicate PDC bits offer significant potential for reducing geothermal well development costs provided the limitations in their operation are adequately addressed.

Of the five documented tests, three were carried out by the US in low-permeability, natural-gas bearing, sandstone-shale formations, and two were done in the USSR within oil-bearing carbonates. The objectives of the US stimulation efforts were to increase porosity and permeability in a reservoir around a specific well by creating a chimney of rock rubble with fractures extending beyond it, and to connect superimposed reservoir layers. In the USSR, the intent was to extensively fracture an existing reservoir in the more general vicinity of producing wells, again increasing overall permeability and porosity. In both countries, the ultimate goals were to increase production rates and ultimate recovery from the reservoirs. Subsurface explosive devices ranging from 2.3 to about 100 kilotons were used at depths ranging from 1208 m (3963 ft) to 2568 m (8427 ft). Post-shot problems were encountered, including smaller-than-calculated fracture zones, formation damage, radioactivity of the product, and dilution of the BTU value of the natural gas with inflammable gases created by the explosion. Reports also suggest that production-enhancement factors from these tests fell short of expectations. Ultimately, the enhanced-production benefits of the tests were insufficient to support continuation of the programs within increasingly adversarial political, economic, and social climates, and attempts to stimulate hydrocarbon reservoirs with nuclear devices have been terminated in both countries.

Partners in the project are the US Department of Energy and the Australian Safeguards and Non-Proliferation Office. This project could satisfy a need to have near-real-time continuity of knowledge of a shipment of nuclear material. The benefits of demonstrating a fully operational and sustainable system are significant, because the envisioned system could significantly enhance global safety and security of nuclear material in the transport phases of the nuclear fuel cycle.

Public health concerns require that some assessment of the potential for further plume movement in the future be made. Reaction-transport models, which might conceivably be used to predict plume movement, require extensive data inputs that are often uncertain. Many of the site-specific inputs are physical parameters that can vary spatially and with time. Limitations in data availability and accuracy means that reaction-transport predictions can rarely provide more than order-of-magnitude bounding estimates of contaminant movement in the subsurface. A more direct means for establishing the limits of contaminant transport is to examine actual plumes to determine if, collectively, they spread and attenuate in a reasonably consistent and characteristic fashion. Here a number of U plumes from ore bodies and contaminated sites were critically examined to identify characteristics of U plume movement. The magnitude of the original contaminant source, the geologic setting, and the hydrologic regime were rarely similar from site to site. Plumes also spanned a vast range of ages, and no complete set of time-series plume analyses based on the spatial extent of U contamination exist for a particular site. Despite the accumulated uncertainties and variabilities, the plume data set gave a clear and reasonably consistent picture of U plume behavior. Specifically, uranium plumes: Appear to reach steady-state, that is, they quit spreading, rapidly (within a few years). Exceed roughly 2 km in length only in special cases (e.g., where in situ leaching has been carried out). The majority are much smaller. Exhibit very similar U chemistry between sites. This implies analogous contaminant attenuation mechanisms despite their location.

AN - 72520644; 11140771 AB - Gangliosides, glycosphingolipids present in the membranes of neuronal and other cells, are natural receptors for a number of bacterial toxins and viruses whose sensitive detection is of interest in clinical medicine as well as in biological warfare or terrorism incidents. Liposomes containing gangliosides mimic cells that are invaded by bacterial toxins and can be used as sensitive probes for detecting these toxins. We discuss detection of three bacterial toxins-tetanus, botulinum, and cholera toxins using ganglioside-bearing liposomes. Tetanus and botulinum toxins selectively bind gangliosides of the G1b series, namely, GT1b, GD1b, and GQ1b; and cholera toxin binds GM1 very specifically. Unilamellar liposomes containing GT1b or GM1 as one of the constituent lipids were prepared by extrusion through polycarbonate membranes. To impart signal generation capability to these liposomes, fluorophore-labeled lipids were incorporated in the bilayer of liposomes. The fluorescent liposomes, containing both a marker (rhodamine) and a receptor (GT1b or GM1) in the bilayer, were used in sandwich fluoroimmunoassays for tetanus, botulinum, and cholera toxins and as low as 1 nM of each toxin could be detected. The apparent dissociation constants of liposome-toxin complexes were in 10(-8) M range, indicating strong binding. This is the first report on detection of tetanus and botulinum toxins based on specific recognition by gangliosides. The fluorescent liposomes are attractive as immunoreagents for another reason as well--they provide enormous signal amplification for each binding event as each liposome contains up to 22,000 rhodamine molecules. The present approach using receptors incorporated in bilayers of liposomes offers a unique solution to employ water-insoluble receptors, such as glycolipids and membrane proteins, for sensitive detection of toxins and other clinically important biomolecules.

The function g is proportional to the residence time distribution in the immobile domain; we tabulate g for many geometries, including several distributed (multirate) models of mass transfer. Using this expression, we examine the behavior of late-time concentration for a number of mass transfer models. One key result is that if rate-limited mass transfer causes the BTC to behave as a power law at late time (i.e., C approximately t (super -k) ), then the underlying density function of rate coefficients must also be a power law with the form alpha (super k-3) as a alpha --> 0. This is true for both density functions of first-order and diffusion rate coefficients. BTCs with k < 3 persisting to the end of the experiment indicate a mean residence time longer than the experiment, and possibly an infinite residence time, and also suggest an effective rate coefficient that is either undefined or changes as a function of observation time. We apply our analysis to breakthrough curves from single-well injection-withdrawal tests at the Waste Isolation Pilot Plant, New Mexico. Copyright 2000 by the American Geophysical Union.

By analogy with shear localization, the process is referred to as compaction localization. To gain insight into the process of compaction localization, acoustic emission locations were used to define and track the thicknesses of localized zones of compaction during axisymmetric compression experiments. Zones of acoustic emission, demarcating the boundaries between the uncompacted and compacted regions, developed and moved parallel to the sample axis at velocities an order of magnitude higher than the imposed specimen shortening rate. Thus tabular zones of compaction were found to grow (thicken) in the direction of maximum compressive stress. These structures may form due to tectonic stresses or as a result of local stresses induced during production of fluids from wells, resulting in barriers to fluid (oil, gas, water) movement in sandstone reservoirs.

Lasers are used in laboratory analyses of human blood samples and serve as surgical tools that kill, burn or cut tissue. Recent semiconductor microtechnology has reduced the laser size to the size of a biological cell or even a virus particle. The integration of these ultra-small lasers with biological systems makes it possible to create microelectrical mechanical systems that might revolutionize healthcare delivery.

The heterogeneity structure was designed to be reminiscent of fluvial channel lag cut-and-fill architecture and to contain a series of capillary barriers. As invasion progressed, nonwetting phase structure developed a series of fingers and pools; behind the growing front we found nonwetting phase saturation to pulsate in certain regions when viscous forces were low. Through a scale analysis we derive a series of length scales that describe finger diameter, pool height and width, and regions where pulsation occurs within a heterogeneous porous medium. In all cases we find that the intrinsic pore-scale nature of the invasion process and resulting structure must be incorporated into our analysis to explain experimental results. We propose a simple macroscale structural growth model that assembles length scales for substructures to delineate nonwetting phase migration from a source into a heterogeneous domain. For such a model applied at the field scale for dense nonaqueous phase liquid migration, we expect capillary and gravity forces within the complex subsurface lithology to play the primary roles with viscous forces forming a perturbation on the inviscid phase structure.

When direct matrix inversion is used, the model resolution and a posteriori model covariance matrices can be calculated readily. By analyzing individual columns of the model resolution matrix, the spatial variation of the resolution in the horizontal and vertical directions can be estimated empirically. Plotting the diagonal of the model covariance matrix provides an estimate of how errors in the inversion process, such as data noise and incorrect a priori assumptions, map into parameter error and thus provides valuable information about the uniqueness of the resulting image. Methods are also derived for image appraisal when the iterative conjugate gradient technique is applied to solve the inverse. An iterative statistical method yields accurate estimates of the model covariance matrix as long as enough iterations are used. Although determining the entire model resolution matrix in a similar manner is computationally prohibitive, individual columns of this matrix can be determined. Thus, the spatial variation in image resolution can be determined by calculating the columns of this matrix for key points in the image domain and then interpolating between. Examples of the image analysis techniques are provided on 2-D and 3-D synthetic crosswell EM data sets as well as a field data set collected at Lost Hills oil field in central California.

These downhole arrays offer the significant advantages of being close to the fracture (large signal) and being unaffected by the free surface. As with surface tiltmeter data, analysis of these measurements requires the inversion of a crack or dislocation model. To supplement the dislocation models of Davis [1983], Okada [1992], and others, this work has extended several elastic crack solutions to provide tilt calculations. The solutions include constant-pressure two-dimensional (2-D), penny-shaped, and 3-D-elliptic cracks and a 2-D-variable-pressure crack. Equations are developed for an arbitrary inclined fracture in an infinite elastic space. Effects of fracture height, fracture length, fracture dip, fracture azimuth, fracture width, and monitoring distance on the tilt distribution are given, as well as comparisons with the dislocation model. The results show that the tilt measurements are very sensitive to the fracture dimensions but also that it is difficult to separate the competing effects of the various parameters.

For the case of gibbsite precipitated on a kaolinite powder substrate we demonstrate a simple method having a minimum detection limit of 0.1 wt%, using pure gibbsite as the intensity reference in mechanical mixtures of gibbsite and kaolinite. The amount of gibbsite precipitated onto kaolinite at 80 degrees C, pH 3 is higher when determined from solution chemistry than from the X-ray method, and the difference in amounts increases with increasing Al concentration in solution. This discrepancy can be explained by assuming that a fraction of the precipitated material is effectively invisible to the X-ray diffraction technique, either due to a small diffracting domain size along the gibbsite [001] direction or formation of an Al-phase that is amorphous to X-rays. This method should be generally useful for a range of mineral mixtures where at least one intense reflection for the phase of interest is not obscured. The ability to identify, characterize, and quantify trace phases by X-ray diffraction, especially when combined with surface analysis by electron or atomic force imaging, is an important complement to the conventional approach of monitoring solution composition in growth kinetics experiments.

The US Environmental Protection Agency (EPA) is responsible for certifications and regulation of the WIPP facility for the radioactive components of the waste. The EPA has promulgated general radioactive waste disposal standards at 40 CFR Part 191, and WIPP-specific criteria to implement and interpret the generic disposal standards at 40 CFR Part 194. In October 1996, the DOE submitted its Compliance Certification Application (CCA) to the EPA to demonstrate compliance with the disposal standards at Subparts B and C of 40 CFR Part 191. This paper summarizes the development of the overall legal framework for radioactive waste disposal at the WIPP, the parallel development of the WIPP performance assessment (PA), and how the EPA disposal standards and implementing criteria formed the basis for the CCA WIPP PA. The CCA resulted in a certification in May 1998 by the EPA of the WIPP's compliance with the EPA's disposal standard, thus enabling the WIPP to begin radioactive waste disposal.

The presented results indicate that radionuclide and colloid transport in the Culebra Dolomite does not constitute a serious threat to the effectiveness of the WIPP as a disposal facility for transuranic waste. Even when the effects of uncertain analysis inputs are taken into account, no radionuclide transport to the boundary with the accessible environment was observed; thus, the associated CCDFs for comparison with the boundary line specified in the US Environmental Protection Agency's standard for the geologic disposal of radioactive waste (40 CFR 191, 40 CFR 194) are degenerate in the sense of having a probability of zero of exceeding a release of zero.

Approximately 35% of the TRU waste is currently packaged and stored (i.e. legacy) waste, with the remainder of the waste to be packaged or generated and packaged in activities before the year 2033, which is the closure time for the repository. These wastes were produced at 27 U.S. Department of Energy (DOE) sites in the course of generating defense nuclear materials. The radionuclide and nonradionuclide inventories for the TRU wastes described in this paper were used in the 1996 WIPP Compliance Certification Application (CCA) performance assessment calculations by the Sandia National Laboratories/New Mexico (SNL/NM).

Fracture intensities (spacings) along the sinuous channels are also only loosely related to channel orientation. Theory, however, would suggest that stresses, and therefore natural fracture patterns such as orientation and intensity, should vary within a sinuous lenticular body enclosed in a shale. These variations should be a function of 1) the differential between the mechanical properties of the sandstone and the shale, and 2) the changing relative orientation between the axis of a sinuous lens and the regional stresses. The discrepancy between observation and theory is In part due to the heterogeneous, sandstone to conglomeratic composition of the Cedar Mountain lenses, which appears to be a more important factor than lens orientation within the stress field. Plots of fracture spacing relative to lens orientation, to grain size, and to mechanical bed thickness, show only irregular trends. A younger set of widely-spaced, unmineralized fractures that trend sub-parallel to the meandering channel axes is also present in the Cedar Mountain sandstones. These fractures were superimposed by gravitational valley-wall stresses and by mobility of the underlying shales during exhumation of the channel axes, and would not be significant to subsurface reservoir plumbing. Knowledge of such fracture patterns would be important to the maximum efficient recovery of hydrocarbons from lenticular reservoirs such as fluvial channels, incised valley fills, and offshore bars.

Groundwater occurs in both the regional aquifer and in a localized shallow groundwater system. The regional aquifer is Albuquerque's drinking water source and is 500 to 600 ft deep in unconsolidated sediments of the upper unit of the Tertiary Santa Fe Group. Flow direction in the study area is north-northwest toward municipal well fields. The shallow system consists of multiple, perched saturated intervals 175 to 275 ft above the regional aquifer. This system has only been identified in the north-central portion of Sandia and flows southeast. This system does not appear to be hydraulically connected to the regional aquifer. Trichloroethene has been detected in 5 of 12 shallow-system monitoring wells; concentrations exceed regulatory limits at 3 of the 5 locations. Other chlorinated compounds have been detected in some of the 12 wells at concentrations below their respective allowable levels. This low-level contamination is laterally widespread yet discontinuous. To date, investigations of surface releases to identify potential groundwater contaminant sources in the study area are inconclusive, but extensive underground waste-water utilities may have produced a diffuse source.

Two pairs of conjugate shear fractures, one with a bed-parallel axis of intersection and the other with a bed-normal axis of intersection, both with a bed-parallel bisector to the acute angle, are limited to the Dakota Sandstone. These fracture sets and orientations are also observed within core from the San Juan Basin and are compatible with N-S to NNE-SSW shortening in the area studied. Basement-involved thrusts are observed on the eastern, northern and western margins of the basin. The southern extent of the basin is bounded by the Chaco slope, which dips gently basinward, away from the basement-cored Zuni Uplift. Local variability of fracture strike around the basin is common and is interpreted to be due to local variations in the maximum shortening direction and to mechanical stratigraphy. Changes in mechanical stratigraphy that control fracture characteristics are attributed to compositional, diagenetic and depositional variability across the basin. Petrophysical controls on mechanical properties are evidenced by the fact that shear and extension fractures are found in the Dakota Sandstone, whereas only extension fractures are observed in the Mesaverde Group.

This phase is currently the best available model compound for other, typically more disordered, mixed-metal layered hydroxides. The computed crystallographic parameters and density are in good agreement with available X-ray diffraction data and the force field developed for these simulations preserves the structure and density to within less than 2% of their measured values. In contrast to the highly ordered arrangement of the interlayer water molecules interpreted from the X-ray data, the simulations reveal significant dynamic disorder in water orientations. At all simulated temperatures, the interlayer water molecules undergo rapid librations (hindered hopping rotations) around an axis essentially perpendicular to the layers. This results in breaking and reformation of hydrogen bonds with the neighboring Cl (super -) anions and in a time-averaged nearly uniaxial symmetry at Cl (super -) , in good agreement with recent (super 35) Cl NMR measurements. Power spectra of translational, librational, and vibrational motions of interlayer and surface Cl (super -) and H (sub 2) O were calculated as Fourier transforms of the atomic velocity autocorrelation functions and compared with the corresponding spectra and dynamics for a bulk aqueous solution. The ordered interlayer space has significant effects on the motions. Strong electrostatic attraction between interlayer water molecules and Ca atoms in the principal layer makes the Ca...OH (sub 2) bond direction the preferred axis for interlayer water librations. The calculated diffusion coefficient of Cl (super -) as an outer-sphere surface complex is almost three times that of inner-sphere Cl (super -) , but is still about an order of magnitude less than that of Cl (super -) in bulk aqueous solution at the same temperature.

Tracer tests conducted in the Culebra dolomite, a potential groundwater pathway, suggested that a multirate mass transfer model provides the best description of conservative tracer transport for length scales of several to tens of meters. This paper describes independent characterization of the chemical and physical components of actinide retardation; such deconvolution is required to support application of a multirate model to radionuclide transport at the scale of the WIPP site. Transport experiments with 22Na and 232U/238U, using crushed dolomite with different size fractions, have been run at multiple flow rates to constrain intraparticle diffusion rates and aggregate retardation capacity coefficients. Flow-interruption experiments have been carried out with intact cores of fractured dolomite whose pore structures have been characterized with computerized gamma-ray tomography. When advective flow is temporarily interrupted during the experiments, only diffusion occurs in the system and the mass transfer coefficient describing local solute transfer between the advective pore space (fractures) and the non-mobile porosity (matrix) can be measured accurately. Batch experiments are being carried out to determine the dependence of actinide sorption and desorption coefficients on reaction rates, tracer concentrations, and compositions of solution and substrates in the absence of transport. Once an internally- consistent set of chemical and physical parameters is obtained, numerical sensitivity analysis with a mechanistically-based chemical-flow-transport model can examine the effects of key parameter variations on radionuclide transport and allow model simplification for performance assessment.

In the current experimental program, the authors are developing a technical basis for taking credit for the complete set of attributes of MgO in geochemical, hydrogeological, and geomechanical technical areas, resulting in an improved conceptual model for the WIPP such as the following. Water uptake by MgO will delay the development of mobile actinides and gas generation by microbes and corrosion. Reduced gas generation will reduce or even eliminate spallings releases. As MgO hydrates, it swells, reducing porosity and permeability, which will inhibit gas flow in the repository, in turn reducing spallings releases. Hydration will also result in a self-sealing mechanism by which water uptake and swelling of MgO adjacent to a groundwater seep cuts off further seepage. Reaction with some groundwaters will produce cementitious materials, which will help to cement waste particles or produce a cohesive solid mass. Larger particles are less likely to be entrained in a spallings release. If sufficient water eventually accumulates in a repository to support microbial gas generation, magnesium carbonate cements will form; also producing good cohesion and strength.

We use a combination of physical experiments and computational simulations to test a theoretical model in which the effective longitudinal dispersion coefficient D (sub L) is expressed as a sum of the contributions of these three dispersive mechanisms. The combined influence of Taylor dispersion and macrodispersion results in a nonlinear dependence of D (sub L) on the Peclet number (Pe = V/D (sub m) , where V is the mean solute velocity, is the mean aperture, and D (sub m) is the molecular diffusion coefficient). Three distinct dispersion regimes become evident: For small Pe (Pe <1), molecular diffusion dominates resulting in D (sub L) varies as Pe (super 0) ; for intermediate Pe, macrodispersion dominates (D (sub L) varies as Pe); and for large Pe, Taylor dispersion dominates (D (sub L) varies as Pe (super 2) ). The Pe range corresponding to these different regimes is controlled by the statistics of the aperture field. In particular, the upper limit of Pe corresponding to the macrodispersion regime increases as the macrodispersivity increases. Physical experiments in an analog, rough-walled fracture confirm the nonlinear Pe dependence of D (sub L) predicted by the theoretical model. However, the theoretical model underestimates the magnitude of D (sub L) . Computational simulations, using a particle-tracking algorithm that incorporates all three dispersive mechanisms, agree very closely with the theoretical model predictions. The close agreement between the theoretical model and computational simulations is largely because, in both cases, the Reynolds equation describes the flow field in the fracture. The discrepancy between theoretical model predictions and D (sub L) estimated from the physical experiments appears to be largely due to deviations from the local cubic law assumed by the Reynolds equation.

Ongoing technical programs at the facility support requirements regarding continued demonstration of compliance with regulations and improvements to operational efficiency. One factor that can be important to performance measurements at WIPP is the volume of fluid flowing into the repository. The objective of the analysis presented in this paper is to address those processes that influence liquid inflow to the waste disposal areas. Simulations focus on the coupling between brine inflow and properties of the proximal damaged zone in the host rock. Calculations show that significant reduction in predicted brine inflow results when two-phase flow properties of the damaged zone are modified relative to baseline values. Results warrant further investigation regarding these properties. The study also indicates that only nominal improvement to predictive capabilities would result from using a fully coupled transient approach to simulate development of damage in the host rock.

At the Pecos mine, New Mexico, drainage near the waste rock pile is acidic (pH 3.0-5.0) and carries high concentrations of Zn, Al, Cu and Pb. As drainage flows towards the Pecos River, pH increases to > 7 and heavy metal content decreases. A process model of natural attenuation in this drainage shows that the main controls on pH are reaction with a local bedrock that contains limestone, and concurrent mixing with tributary streams. Models that account for both calcite dissolution and mixing reproduce the observed decrease in aqueous metal concentrations with increasing pH. Contaminant concentrations attenuate primarily via two distinct pathways: Al, Cu, Fe and Pb precipitate directly from solution, whereas Zn, Mg, Mn and SO (sub 4) concentrations decrease primarily through dilution. Pb adsorbs to precipitating hydroxide surfaces.

Existing functions such as van Genuchten [1980], Brooks and Corey [1966], and Luckner et al. [1989] have significant limitations in the dry region as the liquid saturation goes to zero. This region, which is important in a number of applications, including liquid and vapor flow and vapor-solid sorption, has been the subject of a number of previous investigations. Most previous studies extended standard capillary pressure curves into the adsorption region to zero water content and required a refitting of the revised curves to the data. In contrast, the present method provides for a simple extension of existing capillary pressure curves without the need to refit the experimental data. Therefore previous curve fits can be used, and the transition between the existing fit and the relationship in the adsorption region is easily calculated. The data-model comparison shows good agreement. This extension is a simple and convenient way to extend existing curves to the dry region.

DOE will receive, treat, and temporarily store Al-SNF, most of which is composed of highly enriched uranium, as its Savannah River Site in South Carolina. DOE intends ultimately to send the treated Al-SNF to a geologic repository for permanent disposal. DOE initially considered ten treatment alternatives for the management of Al-SNF, and has narrowed the choice of two of these: the direct disposal and melt and dilute alternatives. The decision analysis presented in this document focuses on a formal decision process used to evaluate these two remaining alternatives.

Gamma ray computerized tomography created three-dimensional grids of bulk density and macropore index over volumes from 1.4 X 10 (super -7) to 1.6 L. Three different methods for both volume averaging and REV analysis were applied and compared. Both density and macropore index converged to single values with increasing volume, which meets the most common qualitative definition of a REV. Statistical test results for the relatively homogeneous samples indicate that volumes larger than 1 to 7 mL have constant properties. Contrarily, a highly varied sample required 250 and 373 mL to achieve invariant density and macropore characteristics, respectively. Prismatic volume averaging was found to be better than slice averaging, while a qualitative test for the REV provided similar results as a rigorous statistical method. All cores were larger than the REV but were significantly different from one another. This implies that multiple cores are necessary to determine the entire range of transport properties within the rock. Copyright 2000 by the American Geophysical Union.

We develop a 1-D inversion algorithm that can invert data from the horizontal coplanar (HC), vertical coplanar, coaxial (CA), and perpendicular coil configurations separately or jointly. The inverse problem is solved by minimizing a model objective function subject to data constraints. Tests using synthetic data from 1-D models indicate that if data are collected at a sufficient number of frequencies, then the recovered models from individual inversions of different coil systems can be quite similar. However, if only a limited number of frequencies are available, then joint inversion of data from different coils produces a better model than the individual inversions. Tests on 3-D synthetic data sets indicate that 1-D inversions can be used as a fast and approximate tool to locate anomalies in the subsurface. Also for the test example presented here, the joint inversion of HC and CA data over a 3-D conductivity provided a better model than that produced by the individual inversion of the data sets.

The computing cost of shot-record migration is the product of the number of shots in the survey and the expense of each individual migration. Many attempts to reduce this cost have focused on the speed of the individual migrations, trying to achieve a better trade-off between accuracy and speed. Another approach is to reduce the number of migrations. We investigate the simultaneous migration of shot records using frequency-domain shot-record migration algorithms. The difficulty with this approach is the production of so-called crossterms between unrelated shot and receiver wavefields, which generate unwanted artifacts or noise in the final image. To reduce these artifacts and obtain an image comparable in quality to the single-shot-per-migration result, we have introduced a process called phase encoding, which shifts or disperses these crossterms. The process of phase encoding thus allows one to trade S/N ratio for the speed of migrating the entire survey. Several encoding functions and two application strategies have been tested. The first strategy, combining multiple shots per migration and using each shot only once, reduces computation in direct relation to the number of shots combined. The second strategy, performing multiple migrations of all the shots in the survey, provides a means to reduce the crossterm noise by stacking the resulting images. The additional noise in both strategies may be tolerated if it is no stronger than the inherent seismic noise in the migrated image and if the final image is achieved with less cost.

The Lisburne is relatively undeformed in the Lisburne field, but future exploration plays in the Lisburne may be closer to the mountain front, where the Lisburne is both detachment folded and thrust faulted. Detatchment folds in the Lisburne Group are widely exposed in the northeastern Brooks Range, making it an ideal natural laboratory for study of the character and distribution of fractures as a function of mechanical stratigraphy and position within a detachment fold. Relatively undeformed or mildly deformed Lisburne display two distinctive fracture sets: an early NNW-oriented set of extension fractures and a later EW-oriented set of extension and shear fractures. The fracture character and distribution in both sets are clearly linked to carbonate lithology, with fine-grained lithologies having higher fracture densities than coarser lithologies. Within each set, the fracture orientation is very consistent. With folding, the relationship between lithology and fracture density remained unchanged. However, when compared to fold limbs, the fracture densities in fold hinges are higher in all lithologies, and show greater vertical extent. Both fracture sets become more variable in orientation and character in fold hinges, with greater numbers of conjugate fracture sets and shear fractures. The relative timing of the two fracture sets becomes more ambiguous, with NNW-oriented fractures not always clearly predating E-W-oriented fractures. Other structures that would potentially destroy permeability, such as dissolution cleavage, also occur in hinge areas. These observations suggest that structural position in detachment folded carbonates play a major role in determining reservoir character.

This system currently supports production of 12-20 MMCFG/D from a depth of 15,000 ft, despite the average matrix permeability of only 25 md. 76 natural fractures occur in the cores, suggesting an average fracture spacing of one ft. However, spacing ranges from less than an inch to nearly 17 ft. Moreover, spacing is facies-dependent: fracture intensity in the first two cores is only a third of that in the third core, 250 ft downhole and in a finer-grained facies. There are two near-vertical fracture sets: an east-west set striking about 100 degrees , and a younger, north-south set striking about 5 degrees . The older, east-west trending fracture set is mineralized with an early, quartz druze, a younger carbon film, and a youngest patchy to covering kaolinite. Geometries indicate that this set opened in extension, but 30-50% of the individual fractures have been reactivated in right-lateral, oblique shear. Shear reactivation occurred during activity on an underlying, basement-involved thrust and associated tear faults. The younger, north-south fracture set is also mineralized with quartz druze, although the larger crystal habit suggests a different phase of precipitation.

Results include: (1) Cost for drilling deeper than 15,000' reduced to 50% below the previous industry average; (2) Over 400 fractures intersected in a 1750' horizontal leg (14,950' TVD); (3) The deepest horizontal tight-gas sandstone cores in the world; (4) One of the highest gas flow capacities ever encountered in the tight-gas province of the Frontier Formation (14 mmcfd); (5) Initiation of ongoing drilling to exploit this resource. Core, log and production test information from an offsetting well, combined with regional 3-D seismic data were critical to site selection. The reservoir is massive to hummocky cross-stratified, very-fine grained, nearshore-marine sandstone, with 10-12% porosity, 25 microdarcy permeability, and intense fracturing. Fractures in a vertical offset well and in the horizontal RI4-H indicate shear displacement with a dominant strike orientation ranging from 80 to 110 degrees. The fractures are open to partially filled with calcite, quartz, kaolinite and bitumen. Fracture spacing is variable and is most intense near several small faults penetrated by the well. Open fractures which strike east-west, nearly perpendicular to the well bore, occur along the entire length of the well, as observed in core and microresistivity images. Dissoultion of feldspar and lithic grains along microfractures significantly enhances permeability. This project underscores the value of government and industry research partnerships aimed at solving problems which have eluded industry.

Experiments were performed on four, centimeter-scale slabs of Culebra dolomite taken from the Waste Isolation Pilot Plant (WIPP) site. These tests involved the diffusion of potassium iodide into a single edge of each brine-saturated rock slab, while X-ray absorption imaging was used to measure the two-dimensional relative concentration distribution at different times during the experiment. X-ray imaging was also used to measure the heterogeneous, two-dimensional porosity distribution of each rock slab. The resulting high-resolution data provide unique insight into the spatially varying diffusion characteristics of each heterogeneous rock sample, which traditional methods such as through-diffusion experiments cannot. In these tests, significant variations in the diffusion coefficient were calculated over the relatively small length (centimeter) and time scales (months) investigated. Results also indicated that these variations were related to the heterogeneous porosity characteristics of each rock sample. Not only were the diffusion coefficients found to depend on the magnitude of the porosity but also on its spatial distribution. Specifically, the geometry, position, and orientation of the heterogeneous porosity features populating each rock slab appeared to influence the diffusion characteristics.

A prevalent form is fragmented DU originating from various scientific tests involving high explosives and DU during weapon development programs, at firing practice ranges, or war theaters where DU was used in armor-piercing projectiles. The contamination at these sites is typically very heterogeneous, with discreet, visually identifiable DU fragments mixed with native soil. That is, the bulk-averaged DU activity is quite low, while specific DU fragments, which are distinct from the soil matrix, have much higher specific activity. DU is best known as a dark, black metal that is nearly twice as dense as lead, but DU in the environment readily weathers (oxidizes) to a distinctive bright yellow color that is readily visible. While the specific activity (amount of radioactivity per mass of soil) of DU is relatively low and presents only a minor radiological hazard, the fact that it is radioactive and visually identifiable makes it desirable to remove the DU "contamination" from the environment.

ALE methods include the ability to treat shock waves in gases, liquids and solids and the interaction of shock waves with each other and with media from one of the other categories. ALE codes can also treat explosive detonation and the expansion of the explosive gases and their interaction with air and solids. ALEGRA is a 3-D ALE code that has been developed at Sandia National Laboratories over the past few years. ALEGRA has been applied to a 2-D simulation of presplitting using decoupled explosives in rock blasting with very interesting results. The detonation of the explosive at the bottom of the hole sends a shock wave up the borehole driven by the explosive gas expanding into air. The explosive gas compresses the air against the stemming column where it rebounds and recompresses at the bottom of the borehole. This type of ringing takes several cycles to damp out. The explosively induced expansion of the borehole is also treated by ALEGRA as well as the shock wave imparted to the rock. The presentation of this paper will include several computer animations to aid in understanding this complex phenomenon.

We use effective media theory to develop a conceptual model for satiated relative permeability, then compare predictions to existing experimental measurements, and numerical solutions of the Reynolds equation on the measured aperture field within the flowing phase. The close agreement among all results and data show that for the experiments considered here, in-plane tortuosity induced by the entrapped phase is the dominant factor controlling satiated relative permeability. We also find that for this data set, each factor in the conceptual model displays an approximate power law dependence on the satiated saturation of the fracture.

AN - 85237614; pmid-10655646 AB - We derive a lumped-element, equivalent-circuit model for the thickness-shear mode (TSM) resonator with a viscoelastic film. This modified Butterworth-Van Dyke model includes in the motional branch a series LCR resonator, representing the quartz resonance, and a parallel LCR resonator, representing the film resonance. This model is valid in the vicinity of film resonance, which occurs when the acoustic phase shift across the film is an odd multiple of pi/2 rad. For low-loss films, this model accurately predicts the frequency changes and damping that arise at resonance and is a reasonable approximation away from resonance. Elements of the parallel LCR resonator are explicitly related to film properties and can be interpreted in terms of elastic energy storage and viscous power dissipation. The model leads to a simple graphical interpretation of the coupling between the quartz and film resonances and facilitates understanding of the resulting responses. These responses are compared with predictions from the transmission-line and Sauerbrey models.

Pair-potentials for Ca (super 2+) ions and C and O comprising the carbonate molecular ion were simultaneously fitted to experimental lattice, elastic, dielectric, and vibrational data for calcite, and the structure and elastic properties of aragonite. The resulting potential parameters for the CO (super 2-) (sub 3) group were then transferred to models for the structures and bulk moduli of the carbonate minerals incorporating Mn, Fe, Mg, Ni, Zn, Co, Cd, and thus a fully consistent set of interaction parameters for calculating the properties of the carbonate minerals was obtained. Defect energies for doping the divalent cations into the calcite structure, and for calcium and carbonate ion vacancies were calculated. In addition, various disorder types for dolomite, including anti-site defects, stacking defects, and the energy related to increasing the Ca/Mg ratio in the dolomite structure were simulated. The theoretical enthalpy for dolomite ordering (34.4 kJ/mol) compares very well with experimental measurements.

The first step in building scientific confidence in repository behavior, over time spans long compared to human experience, was through a careful and open site selection process that incorporated an evaluation of the nature and history of geologic processes in the site vicinity. A sound understanding of the geology and hydrology enabled a confident prediction of natural geotechnical behavior over the relatively short geologic time spans required of repository performance.A second set of issues that had then to be addressed was: "How will the excavated repository and its emplaced waste interact with and perturb the natural geotechnical processes?" To develop the desired level of assurance required systematic consideration of all interactions that can occur, individually and in combination. The mechanistic behavior of some processes was poorly known which led to greater uncertainty in performance prediction. To address this shortcoming, formal elicitation of information from experts assured the best possible understanding and modeling based on current knowledge. Finally, review of the process and results by independent, knowledgeable experts provided an assessment of the validity of the conclusions and thus enhanced confidence in the final assessment. In a formal effort to assess where additional investigations could be most beneficial, performance assessment modeling was used to assess sensitivity and uncertainty of the results to various models, assumptions and parameter ranges. If the potential for greater confidence in safety was not substantially affected by the likely outcome of a particular further study, then that area of study was not supported by the result and resources were redirected to investigations that would have greater potential for reducing uncertainty in long-term repository performance.

Understanding is greatly facilitated through experimentation where system response to imposed boundary conditions is measured. While field experiments are critical, they are often of limited usefulness due to unknown property variability, poor experimental control, and the impossibility of true systematic experimentation. Laboratory experimentation allows basic scientific understanding of discrete and coupled processes to be built systematically with a straightforward advance from simple to complicated. We have developed a series of laboratory scale experimental systems to study flow and transport within heterogeneous porous media, fractures, and fracture networks. These experimental systems "work around" various logistical problems in order to achieve high quality, high resolution data while being able to control material properties, their variability and initial and boundary conditions. Many of these experimental system make use of imaging techniques based on the transmission of visible light in transparent/translucent materials. These techniques are capable of acquiring an entire two-dimensional fields integrated across the thin dimension of the experimental system in a few seconds; high resolution CCD cameras (up to 4096 gray levels in 2048X2048 pixel format), feedback stabilized energy sources, and tight experimental control are required to make repeatable quantitative measurements.

Laboratory experiments were designed using sodium chloride and sucrose solutions in a Hele-Shaw cell. A high resolution, full field, light transmission technique was used to study the development of the instability. The initial buoyancy ratio, which is a ratio of fluid density contributions by the two solutes, was varied systematically in the experiments so that the range of parameter space spanned conditions that were nearly stable (buoyancy ratio = 2.8) to those that were moderately unstable (buoyancy ratio = 1.4). In systems of low buoyancy ratio, fingers develop within several minutes, merge with adjacent fingers, form conduits, and stall before newer-generated fingers travel through the conduits and continue the process. Solute fluxes in low buoyancy ratio systems quickly reach steady state and are on the order of 10E-6 m (super 2) /sec. In the higher buoyancy ratio experiments, fingers are slower to evolve and do not interact as dynamically as in the lower buoyancy ratio systems. Our experiment with initial buoyancy ratio of 2.8 exhibited flux on the order of that expected for a similar diffusive system, although the structures were very different than the pattern of transport expected in a diffusing system. Mass flux decayed as the square root of time in two experiments each with initial buoyancy ratio of 2.4 and 2.8.

Numerical simulations of one-dimensional radionuclide transport are performed for the domain relevant to repository performance assessment using the two alternative conceptual approaches. Dual-porosity solute transport modeling produces similar results to effective-porosity modeling for fracture spacing of less than approximately 1 m and greater than about 200 m, which corresponds to values of effective porosity equal to the matrix porosity and the fracture porosity, respectively. For intermediate values of fracture spacing, the dual-porosity approach results in concentration breakthrough curves that differ significantly from the effective-porosity approach and are characterized by earlier first arrival, greater apparent dispersion, and lower concentrations at later times. The effective-porosity approach, as implemented in recent performance assessment analyses of saturated zone transport at Yucca Mountain, is conservative compared to the dual-porosity approach in terms of both radionuclide concentrations and, generally, travel times.

Mary's concern that preferential flow paths controlled both bulk flow and contaminant migration in sand and gravel aquifers led her to search for geologically based methods to describe the internal structure of these materials. Her articulate description of sedimentary facies models as just such a tool laid the conceptual foundation for their use in glaciofluvial and other sedimentary systems. However, a skeptical geological community who felt that each geological system was unique and therefore impossible to describe in any simple manner did not immediately embrace this concept. Additional resistance came from those whose background tended toward formal spatial statistical approaches for describing heterogeneity. Nevertheless, Mary persisted in pursuing research through her graduate students to both apply the concept to descriptive problems and to integrate facies architecture descriptions in numerical simulation. She also espoused the concept broadly through a series of presentations and papers over the last decade. As a result, the concept has now been applied to numerous sedimentary systems for both hydrologic and petroleum purposes. Its expanding use as a fundamental tool of hydrogeologic interpretation and its role in development of new numerical simulation tools clearly shows the valuable contribution of this simple idea. The presentation will trace the development of the basic concept, its growing application within hydrogeological circles and the critical derivative achievements spawned by this pioneering effort.

We assume that future eruptions will be similar to the Lathrop Wells volcano (c. 80 ka). This forms the basis for probability distributions of major element and volatile compositions (dominated by H2O, which likely lies between 1-3 wt%), as well as magma density and viscosity. We assume that an igneous event that is sufficiently shallow (350 m) to intersect the potential repository will always result in eruption. The event will be characterized by the propagation of a dike set from depth, followed by focusing of flow into one or more roughly cylindrical conduits. Estimated conduit diameters range from 15-150 m with a mean of 50 m. For events where an eruptive center and conduit form at the potential repository, we assume that all waste packages intersected by the conduit are damaged and erupted. Although an actual eruption would have phases of relatively low-violence activity, we simplify the calculations so that all entrained waste is dispersed in an explosive eruption column with characteristics that are determined by observations of analogous eruptions historically around the world. Atmospheric dispersion calculations predict a mean ash thickness of 2.3 cm and a mean radionuclide concentration of 2.8e-6 g/cm2 at 20 km from the volcanic vent. For repository designs that include backfill, we predict that disruption will be limited to three waste packages on either side of a dike. For designs where drifts have no backfill, a larger number of waste packages could be damaged. Radiological consequences from subsequent groundwater transport may be as important as those from eruptive dispersal.

Transmitted light techniques allow high resolution visual observation of what's going on inside the test chamber. Digital image analysis allows quantitative interpretation of experimental results. We have conducted a series of experiments that illustrate DNAPL migration behavior. Variations in media textures of the facies that the DNAPLs encountered formed a series of capillary barriers that profoundly influenced the migration path. As the migration progressed, the DNAPL became configured into a series of fingers and pools. We have used this experimental work to test our ability to simulate DNAPL migration using an invasion percolation model. Excellent agreement between the experiments and the simulations demonstrates that the percolation model does a superior job of capturing the physics of the DNAPL migration process. Success of this or any modeling approach is strongly dependent upon adequate representation of the underlying geology. We have conducted several DNAPL remediation experiments using surfactants to increase solubility and an oxidant (permanganate) to chemically degrade the DNAPL. Photographs, digital image analysis, and animations illustrate previously unobserved interactions between the remedial agents and the DNAPL. In the surfactant experiments, we found that DNAPL configured in a series of pools was much more easily inadvertently mobilized than previously hypothesized due to local reductions in interfacial tension (IFT) created when the surfactant flood front encounters a pool. In one experiment, extreme reductions of IFT resulted in mobilization into low permeability regions thus confounding the remediation process. In another experiment using a different surfactant, modest reductions in IFT resulted in more modest mobilization and reasonable DNAPL solubilization. In the permanganate experiment, reaction of potassium permanganate solution with the DNAPL resulted in precipitation of manganese dioxide, a reaction product, which formed a low permeability rind around the DNAPL pools isolating them from further oxidation. From this work, we have learned that failure to explicitly consider the impacts of geologic architecture in remedial design can lead to failure of the remediation.

Although channeling and fingering of flow have been observed in laboratory settings, current models of flow through fractured rock in the unsaturated zone at Yucca Mountain are based on dual-continuum models, which restrict the channeling of flow to grid-block-sized paths (typically on the order of tens to hundreds of meters). A new method has been implemented to extract a discrete weep spacing for each element in the continuum model to provide more realistic simulations of discrete fracture flow paths. The weep spacing is calculated as the distance that separates actively flowing fractures, which is typically larger than the geometric spacing of fractures used in the development of the continuum model. The weep spacing can be derived from dual-continuum models assuming saturated fractures or unsaturated fractures, which yield upper and lower bounds, respectively. The calculated weep spacing can then be used to provide an estimate of flow channeling or focusing for use in drift-seepage models for performance assessment. Current results show that this method can focus the flow in drift-seepage models by a factor of nearly 50. While this tends to increase the flow rate in regions where seepage occurs, the fraction of seepage events may actually decrease because the seepage events are isolated to fewer locations.

Total System Performance Assessment (TSPA) analyses provide a quantitative evaluation of the expected future behavior and risks associated with the potential repository. Numerical simulations of groundwater flow and radionuclide transport in the SZ for TSPA are performed with the SZ site-scale flow and transport model using the FEHM computer program. Radionuclide mass transport simulations are conducted with a particle-tracking algorithm that includes advection, dispersion, fracture/matrix diffusion, sorption, and colloid-facilitated transport. Simulated radiological dose is calculated in the TSPA from the average concentrations of radionuclides in the groundwater supply of a hypothetical farming community located 20 km downgradient of the repository. Preliminary results of the modeling indicate that migration through the SZ takes on the order of hundreds of years for non-sorbing radionuclides and up to tens of thousands of years for sorbing radionuclides. However, significant uncertainties in groundwater flow and radionuclide transport in the SZ system exist and are incorporated in the TSPA analyses through probability distributions for uncertain parameters. Reduction of uncertainty in key parameters is being accomplished with drilling, well testing, and a tracer testing program in the alluvium.

These models reflect a significant interplay between heterogeneity and uncertainty. Heterogeneity reflects the actual variability of rock properties with spatial position-- or example with respect to proximity to the source volcanic caldera(s) or to vertical position within a cooling and degassing pyroclastic deposit. Uncertainty, on the other hand, represents potential differences in the modeled properties at all locations other than the positions of actual sample measurements (either core or geophysical). The stochastic geostatistical methods used in modeling the site make use of the existence of spatial correlation, the tendency of samples collected close together to resemble one another more than samples collected at progressively greater separation distances. Spatial correlation patterns have been shown to be dependent on geologic unit and to be anisotropic in three dimensions. Heterogeneity, as captured by these stochastic models, appears to consist of two components. (1) Large scale changes visible in "averaged" properties are presumably related to subregional geologic processes that may, in some geologic modeling schemes, be represented by multiple, complexly layered stratigraphic subdivisions or by lateral "facies" concepts. (2) Smaller-scale changes in material properties within these models are most likely a function both of local-scale geologic processes (such as pre-existing topography, local inhomogeneities in initial pumice or volatile content, or post-emplacement alteration) and of irresolvable uncertainty related to less-than-exhaustive physical sampling and observation. Because the material properties of the rock mass are "fixed" only at the locations of drill hole or outcrop observation, the effects of uncertainty are most pronounced at positions intermediate between drill hole locations. However, uncertainty is also a function of the observed range of measured values, which can be significant even for a group of presumably closely related samples, and of the inherent geologic heterogeneity that is the underlying cause of that sampled variability. Differences between the scale of the physical measurements and of the downstream use of these property models in numerical models of ground-water flow and radio nuclide transport also complicate use of these data.

XBGPR data are being collected between five wells located along a 11-m profile. The wells span a 3-by-3-m infiltrometer which is producing a constant flux of 2.5 cm of water per day. This flux rate yields unsaturated flow conditions within the sediments at the site. The XBGPR data are first converted to velocity images via a non-linear travel time inversion scheme, next to apparent dielectric constant, and finally to images of moisture content using an empirical relationship derived from laboratory time domain reflectometry (TDR) measurements made on samples collected at the site. This empirical relationship was employed rather than Topp's equation due to the presence of magnetic minerals in the soils. The results indicate that the XBGPR images map the progress of the infiltration as it occurs. In addition, although some lateral smearing is apparent in the images, the XBGPR derived moisture contents compare well with calibrated borehole neutron-log data. XBGPR data acquisition and imaging will continue until the hydrologic system is verified to have reached steady state.

With the advent of geographic information systems (GISs) large quantities of data required to describe transport routes, which may extend to hundreds of kilometres, with high resolution (e.g. 1 km segments) can be handled without inordinate expense. This capability has raised a question concerning the maximum resolution of available input data and compatibility with RADTRAN computational modelsu Quantitative examinations are presented of spatial resolution issues in the calculation of incident-free doses and accident dose risks. For incident-free calculations, the effect of decreasing route-segment length on accuracy, in view of the model employed, is examined, and means of reducing total data input to the RADTRAN calculations, without loss of meaningful resolution of population concentrations, are presented. In the case of accident-risk calculations, the ability to detail population density under very large dispersal plumes permits comparison of plume modelling to actual data. In both types of calculations, meaningful limits to geographic extent are suggested.

The measurements included visible band photometry on both events, as well as filtered 5890 Aa all-sky images of the Na airglow. Also, for the 3:06 A.M. event, we obtained an infrasound measurement of the hydrodynamic yield. For the 1:32 A.M. event, we obtained a set of visible band charge-coupled device (CCD) camera images of the meteor train for times extending to 30 min after the initial impact. The measurement results have been combined to derive an optical efficiency for the intense early-time optical flash, and the total explosion yields and masses for both of the meteors. We have also done a set of numerical radiation, hydrodynamic, and chemistry computations to investigate the nature and distribution of the long-lasting airglow. We attribute the brightest visible airglow to atomic O 5577 Aa line emission, with additional contributions from atomic Na emission and NO (sub 2) chemiluminescence. The near-infrared atmospheric bands of molecular O (sub 2) should be very strong as well. All of the band emissions are expected to show a hollow limb-brightened structure.

We employ a light transmission technique with well-defined accuracy ( approximately 1% error) to measure aperture fields at high spatial resolution ( approximately 0.015 cm). A Hele-Shaw cell is used to confirm our approach by demonstrating agreement between experimental transmissivity, simulated transmissivity on the measured aperture field, and the parallel plate law. In the two rough-walled analog fractures considered, the discrepancy between the experimental and numerical estimates of fracture transmissivity was sufficiently large ( approximately 22-47%) to exclude numerical and experimental errors (<2%) as a source. We conclude that the three-dimensional character of the flow field is important for fully describing fluid flow in the two rough-walled fractures considered and that the approach of depth averaging inherent in the formulation of the Reynolds equation is inadequate. We also explore the effects of spatial resolution, aperture measurement technique, and alternative definitions for link transmissivities in the finite difference formulation, including some that contain corrections for tortuosity perpendicular to the mean fracture plane and Stokes flow. Various formulations for link transmissivity are shown to converge at high resolution ( approximately 1/5 the spatial correlation length) in our smoothly varying fracture. At coarser resolutions the solution becomes increasingly sensitive to definition of link transmissivity and measurement technique. Aperture measurements that integrate over individual grid blocks were less sensitive to measurement scale and definition of link transmissivity than point sampling techniques.

The experiments are made possible by a specially adapted minipermeameter test system. Here we present and analyze 5185 permeability values, corresponding to five different sample supports (i.e., sample volumes) collected from one of the six block faces. The results show that the measured spatial permeability patterns, bimodal permeability distribution, and semivariogram structure/length scales are closely related to the strong textural contrast characterizing the tuff sample (i.e., highly porous pumice fragments embedded in a tight rock matrix). Each of the summary statistics shows distinct and consistent trends with increasing sample support (i.e., upscaling). As the sample support increases, the mean and variance decrease according to a power law relation, and the semivariogram range increases linearly, while the general structure of the semivariogram (isotropic, spherical model) remains unchanged. Interpretation of these results is pursued from two very different points of view; one addresses upscaling of the ensemble statistics, while the second examines upscaling from a local or pointwise perspective. We find the general upscaling trends exhibited by the ensemble statistics (given above) to be consistent with the basic concepts of volume averaging, albeit nonlinear volume averaging. The bimodal characteristics of the tuff sample and the nonuniform flow conditions imparted by the minipermeameter contribute to the nonlinearity. The local analysis reveals strong variability in permeability upscaling from point to point throughout the sampling domain. Specifically, the permeability upscaling exhibited by zones rich in pumice is very different from zones dominated by matrix, unless the averaging volume is significantly larger than the spatial correlation scale.

The solution may be used to obtain the gradient used in calculation of solute transport to a well in a heterogeneous transmissivity field. The solution, obtained using perturbation methods coupled with Green's function techniques, leads us to postulate a more general form of the head for arbitrarily large-variance fields and may be used to obtain moment relations between the log-transmissivity and head under convergent flow conditions when Y(r) is expressed as a random space function. We present expressions for the mean head field when the log-transmissivity is Gaussian and conditioned on the transmissivity value at the well for an arbitrary ln T covariance. Finally, we look at the effect of parameter variations on the mean head behavior and present numerical simulations verifying the second-order mean head expressions.

Mass-balance calculations indicate that 61 % of precipitated calcite in the meromictic Lago di Lugano is redissolved in the water column, and only particles > 40 mu m reach the lake bottom. The dissolution process in deep, meromictic hypolimnions change the size distribution of calcite particles settling through the column, and this is a significant factor in interpreting particle size distributions in lacustrine carbonates as palaeo-indicators.

This condition has the advantage that the adsorbed amount directly follows from the added amount of ions. The macroscopic proton-ion adsorption stoichiometry is defined as the amount of acid consumed upon addition of an oxyanion to the unprotonated form, divided by the amount of the oxyanion adsorbed at constant pH. This stoichiometry is determined mainly by the electrostatic interaction of an ion with the surface.

The aqueous oxidation rate for air saturated water is 2 X 10 (super -12) mol O (sub 2) /m (super 2) /s at steady state; activation energies are 42-44 kJ/mol O (sub 2) over 24-50 degrees C indicating that the oxidation reaction is surface reaction controlled. The oxidation products leaving coal and probably sedimentary organic matter in general, during subaqueous weathering are in the form of CO (sub 2) and DOC.

The results show that at bipy (sub tot) /Cu(II) (sub tot) of one or two, bipy enhances Cu sorption onto the amorphous SiO (sub 2) at a lower concentration of Cu(II) (sub tot) = 0.0001 M, but inhibits Cu sorption at Cu(II) (sub tot) = 0.0016 M. The enhancement or inhibition is more pronounced at higher bipy-to-Cu(II) ratios. It is suggested that Cu(II) and bipy are mutually bonded.

FTIR measurements directly probe vibrations of the EDTA molecule; both diffuse reflectance (DR-TFIR) and attenuated total reflectance (ATR-FTIR) measurements were made. The results suggest that Pb(II)EDTA (super 2-) adsorbs primarily as outer-sphere ions and/or via direct hydrogen bonds to surface functional groups, which displace part of the aqueous solvation shell.

Accurate prediction of complex, multicomponent systems is sensitive to the surface site density used in the model described. Proton and metal cation (Cu(II), Pb(II)) binding to colloidal hematite, and the influence of surface site density on model performance are examined, and the competitive sorption effects between Cu and Pb at the hematite surface, are predicted.

T has a larger effect in NaCl solution than in sea-water, and these differences have been attributed to the effects of natural organic matter on solution complexation and precipitate properties.

Pb, Zn and Cd, which are thus not significantly pyritized, have faster H (sub 2) O exchange reaction kinetics than Fe (super 2+) and form MeS phases prior to FeS formation. Co and Ni have slower reaction kinetics than Fe (super 2+) and are incorporated into pyrite or leached from the pyrite with nitric acid. Hg undergoes chloride complexation which can replace Fe in FeS to form HgS. Cu is reduced by sulphide to form a range of sulphides.

The results are presented using this technique on stearate monolayers adsorbed at the calcite surface from methanolic solutions. From these measurements, details are presented on the in situ structure, bonding, adsorption and growth mechanisms on the monolayers, and the approach can be applied to the interaction of organic molecules with mineral surfaces in aqueous systems.

Dissolved phosphate is delivered to the Dead Sea by diffusion from sediments and by freshwater inflow. From the available data it is not possible to assess whether pollution has affected the dissolved P reservoir. Primary production is only minor and occasional, and removal of dissolved P from the Dead Sea is almost unrelated to biological processes.

The model is tested against available experimental data. Structural data indicate that sorption sites consist of three oxygen atoms around a vacancy in the octahedral layer carrying a charge of 2. The model presented well describes the experimental data; it is generally applicable for highly oxidized synthetic birnessite.

Rigorous system definition limits uncertainty in speciation studies. Experimental uncertainty is discussed with an example of proton interaction in Suwannee River fulvic acid, and a Monte Carlo approach is used to estimate such uncertainty. This technique is recommended for assesssing uncertainty in experimentally determined speciation parameters.

The results are relevant to hazardous waste recovery and remediation in soils. The effect of the ligands on the goethite dissolution rate is not linearly related to the adsorbed coordinating ligand concentration. Comparison of the results with published data suggest that the three hydroxamate groups in desferrioxamine - desferrioxamine D1 coordinate to Fe(III) surface sites relatively independently, with a significant depleting effect of 240 mu M DFO-B or DFO-D1 on Pb(II) adsorption by goethite at pH 6.5; but there is no effect of adsorbed Pb(II) on the goethite dissolution rate.

The study included mineralogical characterization of the arsenates (scorodite, cabrerite-annabergite), geochemical modelling of arsenate solids, precipitation and chemical equilibria, kinetic modelling of arsenate solids dissolution and statistical trends in arsenate concentrations with time. Scorodite and cabrerite-annabergite host most of the As and Ni as the pH is increased with slaked lime; following scorodite precipitation, HFO precipitates and adsorbs most of the remaining As. The results indicate that As concentrations in porewaters are unlikely to exceed 1-2 mg/L even after 10 000 yr of burial in this facility.

Relative to Na, Ca enhances net negative proton charge development, the extent increasing with T. Increasing the background NaCl concentration decreases Ca adsorption. Proton stoichiometries are relatively constant between this T range, suggesting that the processes involved in Ca adsorption do not change with T.

Concentration-depth profiles are presented of dissolved phosphate and fluoride, authigenic P, organic P, Fe-bound P and other parameters. The results indicate that P and porewater fluoride analyses show that disseminated authigenic francolite currently forms on this slope, and accounts for approximately 25 % of the increase with depth in the total organic and Fe-bound P concentrations.

The dissolution rate is proportional to [>Al (sub 2) OH (super +) (sub 2) ] (super 1) , [>AlOH (super +) (sub 2) ] (super 0.5) , and [>Al (sub 2) (super 0-) + AlO (super -) ] (super 3) . A model presented demonstrates the importance of the Al site in the dissolution mechanism and the primary role of the OHs in the basal plane.

Goethite, lepidocrocite, akaganeite and schwertmannite were selected for this study since they occur in varying degrees in a range of weathering environments; also each mineral possesses a different proportion of distinct types of surface sites and all are relatively stable. The results presented show that Cd adsorbs to goethite mainly via a corner-sharing mechanism at low-affinity sites on the dominant (110) surface, and this is achieved by corner sharing with two A-type hydroxyls rather than by one C-type hydroxyl. Goethite morphology precludes significant Cd adsorption at edge-sharing sites.

He is also used as a conservative tracer to constrain the deep-water residence time. The (super 3) He/ (super 4) He isotope ratio of the excess He indicates a flux of mantle-derived magmatic gases into the monimolimnion. The C budget of the water is reassessed and shows that most of the accumulated CO (sub 2) in this region is of magmatic origin. No potentially hazardous accumulation of CO (sub 2) is occurring.

Solution species are measured concurrently with the solid phase. This approach allows the measurement of aqueous and solid species of Co and Mn with surface sensitivity in real time, under hydrodynamic conditions. Of the results, it is shown that the enhanced transport of (super 60) Co by oxidative processes may be lessened by continual exposure to pyrolusite. Mn(III) is formed rather than Mn(II) and alpha -Mn (sub 2) O (sub 3) is formed.

The results demonstrate that the abiotic reduction of uranyl by Fe(II) is catalyzed by specific adsorption of the reactants to mineral surfaces. The effect of Fe(II) adsorption on the potentiometric titration curves of hematite suspensions is consistent with the formation of two surface complexes: identical with FeOFe (super +) and identical with FeOFeOH (super o) ; the contribution of the latter complex to total adsorbed Fe(II) becomes significant at pH > or = 6.5; at pH > or = 8 it represents the predominant Fe(II) surface species.

The results show that water, adsorbed from natural air humidity generates hydrolysis species that are chemi-sorbed to the dangling bonds produced by cleavage of the calcite. These species remain attached even in dry air and in ultra-high vacuum. The adsorbing surface for Ca and CO (sub 3) is the layer of chemi-bonded H and OH, not calcite's bulk termination. Dehydration results in the strong attachment of Ca and CO (sub 3) at the termination of the bulk, where the potential is very high.

The oxidative dissolution is mediated by the binding of the bicarbonate ligand on the initially oxidized U(VI) surface sites, and this is enhanced by T (10-60 degrees C) because of the higher activation energy of surface oxidation compared to surface attachment of the bicarbonate ligand.

The results indicate that the adsorbed NOM reverses the positive charge of the hematite surface for the oppositely charged cases, and imparts additional negative charge to the interface for the similarly charged cases, and are consistent with the contributions of specific interactions between NOM functional groups and surface sites.

The study deals with trace amounts of Cs because of its relevance to nuclear waste management. Sorption on high affinity/low capacity sites was very much slower than sorption on a second type site (4-5 days compared to a few hours in the first type). A third sorption site may be considered when Cs loading is higher than approximately 30 %. Cs sorption on illite at trace amounts various significantly with pH especially under combined acidic or alkaline conditions and low background electrolyte concentrations.

The evidence indicates that the Mn(IV)-oxalate redox reduction proceeds primarily as a transfer of one electron per Mn(IV) centre. Dissolution of birnessite increases with oxalate concentration, which inhibits the more rapid proton-promoted dissolution. XPS data show that Mn(III) is not appreciably reduced by oxalate.

XRD shows kaolinite and smectite at Quintin with micaceous illite, hydroxy-aluminous vermiculite and interstratified minerals, a greater abundance of kaolinite at Fougeres, and equal amounts of kaolinite and illite with chlorite and interstratified minerals at Naizin. Ferric oxides, hematite, goethite or lepidocrocite are well crystallized and belong to the group of Green Rusts; their composition closely follows the variations in the chemical composition of soil solutions, and show the reversibility of the reaction of precipitation and dissolution of Green Rusts.

Dissolved organic matter (DOM) and metal sulphide complexes are the primary factors affecting free Cu in the river samples. Both of these factors showed a seasonal cycle which limited Cu concentrations to sub-nanomolar levels throughout the year. Once the nature of the DOM has been identified, first-order estimates of the free metal ion concentration can be made.

The results indicate that W is concentrated in Mn oxides from oxic sea-water due to its high tendency for polymerization, or the formation of tungstate compounds such as hubnerite and wolframite on the oxide surface. Only a slight correlation is observed between W and Mn, however, perhaps because Mn is oxidatively scavenged from surface water unlike W. The scavenging of Mo by Mn oxide is followed by the release of Mn from reducing sediments.

The results support the selective effects of T on rates of chemical weathering of granites, with the structural release of Si and Na from tetrahedral and octahedral sites in the silicates. Si and Na concentrations in column effluents from weathered granites were much lower than for their fresh counterparts, but showed comparable T effects increasing in concentration by approximately an order of magnitude over 5-35 degrees C.

The calculated pH (sub zpc) decreases with increasing T, but the difference between the pH (sub zpc) (zero point of charge) and the water dissociation constant is not constant over the T range considered. The apparant acidity constants of corundum change over several orders of magnitude between 25 and 70 degrees C, mainly due to a change in the coulombic term, and small T changes could strongly influence the stability of surface complexes.

The main Fe minerals in the precipitates are schwertmannite or schwertmannite-goethite along Imgok creek, and ferrihydrite along Osheep creek. The apparent solubilities of these minerals were estimated from calculated activities of the dissolved species -H (super +) , OH (super -) , Fe (super 3+) and SO (super 2-) (sub 4) . The log of the solubility product of schwertmannite, log K (sub s) , is 10.5 + or - 2.5 at approximately 15 degrees C, and log K (sub f) = 4.3 + or - 0.5.

TEM was used to identify crystallographical features that might influence dissolution in albite, anorthite and labradorite. HAFM and SEM images show various stages of surface attack under varying conditions. The results suggest that an altered layer forms on anorthite despite the lack of bridging Si-O-Si linkages, and the thickness of this layer does not increase continuously but shows steady state behaviour, e.g. by healing of scan fields. There is a distinct junction between this altered layer, showing step-like patterns, and the underlying anorthite.

The results with Fe(III)-chelating ligands and the Fe(III)-reductant suggest a very efficient interference in the electron cycling between Fe(II) and Fe(III) at the pyrite surface. The electron transfer between Fe(III) and pyrite limits the pyrite oxidation rate at pH 7. JF - Geochimica et Cosmochimica Acta AU - Peiffer, Stefan AU - Stubert, Irene A2 - Stipp, Susan L. S.

Competitive adsorption in multi-metal single bacteria systems, single metal systems or multi-metal systems containing two species of bacteria, are measured. The results confirm that the chemical equilibrium approach represents an accurate method for calculating the effects of bacteria on metal adsorption in multicomponent systems not directly studied in the laboratory. Metal adsorption onto bacterial surfaces is an abiotic process; the cell wall does not show preferential or metal-specific adsorption properties.

The results indicate that Cd is surrounded by a first shell of 6 + or - 1 oxygen atoms at 2.3 + or - 0.1 Aa, and a second shell of approximately 2 Fe atoms at 3.8 + or - 0.1 Aa. Cd is inner-spherically bound by bidentate double-corner sharing adsorption on (110) of goethite; it appears to form a precipitate in the presence of citrate and oxalate.

Combining these data with previous work, we see three distinct energetic trends. These represent samples with nearly complete order, nearly complete disorder, and intermediate order. From these trends, the enthalpy of complete disordering is estimated to be 33+ or -6 kJ/mol for MgCa(CO (sub 3) ) (sub 2) and 18+ or -5 kJ/mol for FeCa(CO (sub 3) ) (sub 2) .

In this study, we compare density measurements and ultimate tensile elongation results versus aging time for most of the important generic types of commercial nuclear power plant cable materials. Aging conditions, which include thermal-only, as well as combined radiation plus thermal, were chosen such that potentially anomalous effects caused by diffusion-limited oxidation (DLO) are unimportant. The results show that easily measurable density increases occur in most important cable materials. For some materials and environments, the density change occurs at a fairly constant rate throughout the mechanical property lifetime. For cases involving so-called induction-time behavior, density increases are slow to moderate until after the induction time, at which point they begin to increase dramatically. In other instances, density increases rapidly at first, then slows down. The results offer strong evidence that density measurements, which reflect property changes under both radiation and thermal conditions, could represent a very useful CM approach.

These diagnostic images show that the hydraulic fractures are highly contained for smaller-volume KC1-water injections, but height growth is significant for the larger-volume, higher-rate, higher-viscosity treatments. Fracture lengths for most injections are similar regardless of volume and fluid type.

Here we quantify aperture field measurement error and demonstrate the influence of this error on the results of flow and transport simulations (hypothesized experimental results) through saturated and partially saturated fractures. We find that precision and accuracy can be balanced to greatly improve the technique and present a measurement protocol to obtain a minimum error field. Simulation results show an increased sensitivity to error as we move from flow to transport and from saturated to partially saturated conditions. Significant sensitivity under partially saturated conditions results in differences in channeling and multiple-peaked breakthrough curves. These results emphasize the critical importance of defining and minimizing error for studies of flow and transport in single fractures. Copyright 1999 by the American Geophysical Union.

AN - 85237868; pmid-10450152 AB - To probe directly the analyte/film interactions that characterize molecular recognition in gas sensors, we recorded changes to the in situ surface vibrational spectra of specifically functionalized surface acoustic wave (SAW) devices concurrently with analyte exposure and SAW measurement of the extent of sorption. Fourier transform infrared external-reflectance spectra (FT-IR-ERS) were collected from operating 97-MHz SAW delay lines during exposure to a range of analytes as they interacted with thin-film coatings previously shown to be selective: cyclodextrins for chiral recognition, nickel camphorates for Lewis bases such as pyridine or organophosphonates, and phthalocyanines for aromatic compounds. In most cases where specific chemical interactions--metal coordination, "cage" compound inclusion, or pi-stacking--were expected, analyte dosing caused distinctive changes in the IR spectra, together with anomalously large SAW sensor responses. In contrast, control experiments involving the physisorption of the same analytes by conventional organic polymers did not cause similar changes in the IR spectra, and the SAW responses were smaller. For a given conventional polymer, the partition coefficients (or SAW sensor signals) roughly followed the analyte fraction of saturation vapor pressure. These SAW/FT-IR results support earlier conclusions derived from thickness-shear mode resonator data.

AN - 69464878; 10765425 AB - Calculation of accident dose-risk estimates with the RADTRAN code requires input data describing the population likely to be affected by the plume of radioactive material (RAM) released in a hypothetical transportation accident. In the existing model, population densities within 1/2 mile (0.8 km) of the route centerline are tabulated in three ranges (Rural, Suburban, and Urban). These population densities may be of questionable validity since the plume in the RADTRAN analysis is assumed to extend out to 120 km from the hypothetical accident site. We present a GIS-based population model which accounts for the actual distribution of population under a potential plume, and compare accident-risk estimates based on the resulting population densities with those based on the existing model. Results for individual points along a route differ greatly, but the cumulative accident risks for a sample route of a few hundred kilometers are found to be comparable, if not identical. We conclude, therefore, that for estimation of aggregate accident risks over typical routes of several hundred kilometers, the existing, simpler RADTRAN model is sufficiently detailed and accurate.

The results for pH 3 solutions show that all growth rates obey the same linear function of saturation state provided that the reactive surface area is evaluated for each mineral substrate. This suggests that the dominant nucleation and growth mechanisms are two-dimensional. Kaolinite and muscovite appear to provide epitaxial templates for the growth of gibbsite, although epitaxy may occur only on the edges of kaolinite where there is pH-dependent surface charge, and on both the basal and edges of muscovite where there are permanent and pH-dependent charge, respectively.

Metal adsorption is typically favoured at high pH. Ca and Mg adsorb in near-stoichiometric proportions except at high pH. Their adsorption is diminished at high ionic strengths, pointing to association of Na (super +) with the dolomite surface and the possiblity that Ca and Mg sorb as hydrated, outer-sphere complexes. Sulphate increases sorption of Ca, Mg and possibly Nd. Exchange of Nd for Ca is favoured at high pH and when Ca levels are low. Exchange for Ca appears to control attachment of actinides to dolomite and high levels of Ca (super 2+) in solution decrease adsorption. Provided that sorbing actinide-carbonate complexes do not form, adsorption also decreases at high pCO (sub 2) as Ca (super 2+) levels decrease under such conditions. This effect is observed primarily at and above neutral pH.

This effect, known as the Invar effect, has since been found in various ordered and random alloys and even in amorphous materials. Other physical properties of Invar systems, such as atomic volume, elastic modulus, heat capacity, magnetization and Curie (or Neel) temperature, also show anomalous behaviour. Invar alloys are used in instrumentation, for example as hair springs in watches. It has long been realized that the effect is related to magnetism,; but a full understanding is still lacking. Here we present ab initio calculations of the volume dependences of magnetic and thermodynamic properties for the most typical Invar system, a random face-centred cubic iron-nickel alloy, in which we allow for non-collinear spin alignments--that is, spins that may be canted with respect to the average magnetization direction. We find that the magnetic structure is characterized, even at zero temperature, by a continuous transition from the ferromagnetic state at high volumes to a disordered non-collinear configuration at low volumes. There is an additional, comparable contribution to the net magnetization from the changes in the amplitudes of the local magnetic moments. The non-collinearity gives rise to an anomalous volume dependence of the binding energy, and explains other peculiarities of Invar systems.

LWCEDS is an adaptation of a global system, WCEDS, a matched filtering algorithm for global Comprehensive Test Ban Treaty (CTBT) monitoring applications developed at Sandia National Laboratories and New Mexico Tech. Although the current CTBT monitoring system is based on teleseismic phase detection, effort is being placed on research to highlight specific areas of the globe for which local and regional seismic networks could be employed. An automated waveform correlation regional location system could also serve as a rapid alert and automated location system by providing magnitude and hypocenter information within a few minutes of the occurrence of a hazardous earthquake. In the LWCEDS algorithm, processed waveforms are correlated with theoretical travel-time envelopes, and a grid search is performed to identify the space-time solutions that yield the highest correlations. High correlation indicates that an event has occurred and that a good approximation to the correct origin time and hypocenter has been determined; explicit phase identification is not required. To avoid the large computational expense of calculating a complete correlation for each grid point, we use a laterally homogeneous velocity model and reformulate the problem into a single matrix multiplication and matrix assessment for each time step. LWCEDS has been successfully tested on a suite of local and regional seismic events selected to span the range of expected event quality. Preliminary results from our sparse network show typical epicentral errors of less than 3 km for local events and, with notable exceptions, to within 10 to 20 km for regional events. Similar results were obtained during an on-line experiment conducted to generate daily bulletins during the time period from 3 December 1996 through 7 January 1997. Data from 156 triggers were processed, including 33 teleseisms, 102 regional events (includes explosions), and 21 local earthquakes.

Experiments were conducted for over 600 h, at pH 3 and 6.5, as a function of grain size, and in the presence and absence of a common subsurface bacterial species, Bacillus subtilis. The acid leaching experiments exhibited enhanced Pb mobilities. The contact area between mineral surfaces and water controlled the amount of most elements leached into solution. Typically, bacteria accelerated the leaching of trace elements. However, major element levels were inversely correlated with bacterial content, and generally lower major element concentrations were observed in the presence of bacteria, relative to the bacteria-free systems. This effect was likely caused by bacterial enhancement of secondary mineral precipitation rates. Extremely low concentrations of Pb were leached into solution during the course of the experiments under conditions most closely approximating natural conditions (i.e., near neutral pH). Moreover, the release rate of Pb relative to other elements was low. Pb was associated with iron oxides precipitated in the rock pore spaces, and the experiments suggest that the iron oxides dissolved to a lesser extent than did other minerals in the rock matrix. The mobility of the Pb associated with these iron oxides was less than that of other heavy metals that were likely associated with the surrounding matrix.

The effects caused while the smoke is still in the air have not been explored. Such effects have implications for new digital equipment being installed in nuclear reactors. The US Nuclear Regulatory Commission is sponsoring work to determine the impact of smoke on digital instrumentation and control. As part of this programme, Sandia National Laboratories has tested simple active circuits to determine how smoke affects them. These tests included the study of three possible failure modes on a functional board: (1) circuit bridging, (2) corrosion (metal loss), and (3) induction of stray capacitance. The performance of nine different circuits was measured continuously on bare and conformally coated boards during smoke exposures lasting 1 h each and continued for 24 h after the exposure started. The circuit that was most affected by smoke (100% change in measured values) was the one most sensitive to circuit bridging. Its high impedance (50 M Omega ) was shorted during the exposure, but in some cases recovered after the smoke was vented. The other two failure modes, corrosion and induced stray capacitance, caused little change in the function of the circuits. The smoke permanently increased resistance, of the circuit tested for corrosion, implying that the contacts were corroded. However, the change was very small (<2%). The stray-capacitance test circuit showed very little change after a smoke exposure in either the short or long term. The results of the tests suggest that conformal coatings and type of circuit are major considerations when designing digital circuitry to be used in critical control systems.

These bands were found in association with shear bands and were postulated to be genetically related to them. At the laboratory scale, compaction bands have been noticed in association with boreholes and preexisting, artificial shear cracks subjected to compressive stress fields. Natural compaction bands are noticeable in outcrops because of their resistance to weathering; however, they may be more difficult to discern on freshly cut rock surfaces such as drill core or borehole walls. Because of the much reduced porosity in the compaction bands, these structures are potentially important as permeability barriers in reservoirs and aquifers in porous rocks. For bands associated with boreholes, the crushed material can be washed into the borehole contributing to sand production and possibly altering the stability of the borehole. This paper examines a theoretical framework that explains these features as a constitutive instability leading to localized compaction in a way completely analogous to shear strain localization. Conventional triaxial experiments on Castlegate sandstone resulted in compaction bands. In addition, thick deformation bands having normals at low angles to the maximum compression are present in some specimens. Copyright 1999 by the American Geophysical Union.

This methodology was then applied to two aqueous hazardous waste treatment processes: packed tower aeration and activated sludge (aerobic) biological treatment. The designs achieving 95 percent reliability were compared with those designs based on conventional practice to determine their patterns of conservatism. Scoping-level treatment costs were also related to reliability levels for these treatment processes. The results indicate that the reliability levels for the physical/chemical treatment process (packed tower aeration) based on the deterministic safety factors range from 80 percent to over 99 percent, whereas those for the biological treatment process range from near 0 percent to over 99 percent, depending on the compound evaluated. Increases in reliability per unit increase in treatment costs are most pronounced at lower reliability levels (less than about 80 percent) than at the higher reliability levels (greater than 90 percent, indicating a point of diminishing returns. Additional research focused on process parameters that presently contain large uncertainties may reduce those uncertainties, with attending increases in the reliability levels of the treatment processes.

The ultimate goal is to use the GPR images as input to a 2D hydrologic inversion scheme for recovering the van Genuchten parameters governing unsaturated hydraulic flow. Initial experiments conducted on synthetic data have shown that at least in theory, cross-borehole GPR measurements can provide realistic estimates of the spatial variation in moisture content that are needed for this type of hydrologic inversion scheme. However, the method can not recover exact values of moisture content due to 1) the break down of the empirical expression often employed to convert GPR velocity images to moisture content, and 2) the smearing nature of the imaging algorithm. To test the applicability of this method in a real world environment, cross-borehole GPR measurements were made at a hydrologic/ geophysical vadose zone test site in Socorro, New Mexico. Results show that the GPR images compare well with the uncalibrated borehole neutron log data. GPR data acquisition will continue once an infiltration test has started, and the results from these measurements will be employed in a 2D hydrologic inverse scheme.

For a single well in a homogeneous and isotropic aquifer and under steady state flow conditions, drawdown s is directly related to the pumping rate Q through transmissivity T. In real, nonhomogeneous aquifers, s and Q are still directly related, now through a value called equivalent transmissivity T (sub eq) . In this context, T (sub eq) is defined as the value that best fits Thiem's equation and would, for example, be the transmissivity assigned to the well location in the classical interpretation of a steady state pumping test. This equivalent or upscaled transmissivity is clearly not a local value but is some representative value of a certain area surrounding the well. In this paper we present an analytical solution for upscaling transmissivities under radially convergent steady state flow conditions produced by constant pumping from a well of radius r (sub w) in a heterogeneous aquifer based upon an extension of Thiem's equation. Using a perturbation expansion, we derive a second-order expression for T (sub eq) given as a weighted average of the fluctuations in log T throughout the domain. This expression is compared to other averaging formulae from the literature, and differences are pointed out. T (sub eq) depends upon an infinite series which may be expressed in terms of coefficients of the finite Fourier transform of the log transmissivity function. Sufficient conditions for convergence of this series are examined. Finally, we show that our solution agrees with existing analytical ones to second order and test the solution with a numerical example. Copyright 1999 by the American Geophysical Union.

The three reactive media evaluated included high carbon steel iron fillings, an iron-silica alloy in the form a foam aggregate, and a pellicular humic acid based sorbant (Humasorb from Arctech) mixed with sand. Each material was tested in the laboratory at column scale using simulated site water. All three materials showed promise for the 903 Mound Site; however, the iron filings were determined to be the most cost effective media. In order to validate the laboratory results, the iron filings were further tested at a pilot scale (field columns) using actual site water. Pilot test results were similar to laboratory results; consequently, the iron filings were chosen for the full scale demonstration of this reactive barrier technology. Design parameters including saturated hydraulic conductivity, treatment residence time, and head loss across the media were provided to the design team in support of the final design.

In this paper we present an algorithm for 2-way coupling of flow and geomechanics and indicate what impact the coupled code has on calculation of seismic velocities and density. Each of the simulators, the reservoir simulator from the University of Texas and the geomechanics code from Sandia National Labs, was developed under the US DOE's ACTI program. The codes use 3D finite element discretizations and can be run in parallel. The flow simulator can account for faults and multiple flow models in a single simulation. The geomechanics code models contacts and large, inelastic deformations. We modify the black oil system to include changes in the reservoir geology (porosity) during a single simulation while still maintaining conservation of mass. Modifications to the geomechanics code allow changes in pore pressure to be included in the total stress calculation. The geomechanics code produces volumetric strain-induced porosity updates for the flow simulator. By allowing the two simulators to have different spatial grids and to take different time steps, we are able to account for physical differences in resolution between JF - SEG Annual Meeting Expanded Technical Program Abstracts with Biographies AU - Minkoff, Susan E AU - Stone, C M AU - Arguello, J Guadalupe AU - Bryant, S AU - Eaton, Joe AU - Peszynska, Malgo AU - Wheeler, Mary AU - Anonymous Y1 - 1999 PY - 1999 DA - 1999 SP - 1667 EP - 1670 PB - Society of Exploration Geophysicists, Tulsa, OK VL - 69 SN - 1052-3812, 1052-3812 KW - United States KW - petroleum exploration KW - P-waves KW - offshore KW - data acquisition KW - data processing KW - coupling KW - petroleum KW - fluid phase KW - elastic waves KW - simulation KW - oil and gas fields KW - reservoir rocks KW - California KW - movement KW - time-lapse methods KW - velocity KW - algorithms KW - body waves KW - three-dimensional models KW - graphic display KW - geophysical methods KW - Ekofisk Field KW - mechanical properties KW - deformation KW - seismic methods KW - Belridge Field KW - mathematical methods KW - reservoir properties KW - seismic waves KW - North Sea KW - North Atlantic KW - S-waves KW - Atlantic Ocean KW - 29A:Economic geology, geology of energy sources KW - 20:Applied geophysics UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/913699385?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=SEG+Annual+Meeting+Expanded+Technical+Program+Abstracts+with+Biographies&rft.atitle=Coupled+geomechanics+and+flow+simulation+for+time-lapse+seismic+modeling&rft.au=Minkoff%2C+Susan+E%3BStone%2C+C+M%3BArguello%2C+J+Guadalupe%3BBryant%2C+S%3BEaton%2C+Joe%3BPeszynska%2C+Malgo%3BWheeler%2C+Mary%3BAnonymous&rft.aulast=Minkoff&rft.aufirst=Susan&rft.date=1999-01-01&rft.volume=69&rft.issue=&rft.spage=1667&rft.isbn=&rft.btitle=&rft.title=SEG+Annual+Meeting+Expanded+Technical+Program+Abstracts+with+Biographies&rft.issn=10523812&rft_id=info:doi/10.1190%2F1.1820852 L2 - http://www.seg.org/ LA - English DB - GeoRef N1 - Conference title - Society of Exploration Geophysicists, 69th annual meeting N1 - Copyright - GeoRef, Copyright 2012, American Geosciences Institute.

None of these fracture sets have been reported from the local outcrops of younger strata, and several of the fracture types are anomalous. The fracture assemblage consists of: 1) approximately north-south striking, vertical-extension fractures; 2) more variably oriented but still generally north-trending right-lateral (and rarely left-lateral) vertical, incipient-shear fractures; 3) short, irregularly striking, vertical fractures associated with stylolites; and 4) horizontal shear fractures. Mineralization in the first two types of fractures typically consists of quartz druze overlain by patchy calcite, with local occurrences of kaolinite and barite. Stylolite-related fractures contain exclusively kaolinite, and horizontal shear fractures are typically unmineralized. These fracture sets are interpreted to have formed during deep burial in late Laramide time, under the influence of N-S to NNE-SSW directed compression and pervasive, incipient, right-lateral shearing across the basin. Most fractures of all types have remnant porosity and permeability, and fractures dominate reservoir production. However, the different fracture types are variably developed across the basin as well as within the different facies and members of the Dakota Sandstone. The wide variability in gas production from the Dakota reservoirs is driven by differences in 1) mechanical stratigraphy associated with regional and facies-dependent diagenetic overprints, 2) local structural conditions which impact the in-situ maximum horizontal compressive stress, 3) local developments of interconnected conjugate fracture patterns, and 4) the degree of connectivity between local and regional fracture types.

(super 90) Sr is one of the more common radioactive contaminants and, although the mechanistic controls on uptake by single minerals is well understood, our understanding of its sorption onto and desorption from complex mineral assemblages is incomplete. In this study, we investigate the sorption and desorption of Sr (super 2+) onto quartz, goethite, smectite, and mixtures of the three minerals. A surface complexation model is used to describe sorption and desorption as a function of pH and electrolyte composition. Sorption of Sr (super 2+) onto smectite is strong, pH-independent, and fully reversible, suggesting that cation exchange at the interlayer basal sites is controlling the sorption process. Conversely, Sr sorption onto quartz and goethite is pH-dependent and considerably weaker than that onto smectite. Sorption onto mixtures of smectite, goethite, and quartz is not completely additive, nor is it uniformly reversible. A mechanistic model to explain sorption hysteresis and its implications for in situ extraction of (super 90) Sr will be outlined.

Successful completion of such experiments requires special attention to the physics of fracture flow. The extreme difference in hydraulic response between open fractures and the surrounding matrix suggests caution when applying techniques developed for use in porous media, particularly for unsaturated or multiphase conditions.Data from a field infiltration experiment is analyzed to explore hydraulic response of the fracture network. During the course of a 36 minute ponded infiltration test, approximately 800 liters of water containing a visible tracer (food coloring) were infiltrated into an unsaturated, densely welded, fractured tuff unit from a approximately 2 m diameter infiltration basin (Nicholl and Glass, 1995). Subsequent disassembly of the rock mass to a depth of approximately 5 m below the infiltration surface provided insight that is not typically available. Fractures and spatial distribution of the tracer were mapped on horizontal pavements (2.44X2.44 m) located directly below the infiltration site at approximately 0.5 m vertical intervals. Low permeability of the host rock constrained flow to the fracture network, which was completely flooded at the infiltration surface; flow rates and measured fracture trace lengths suggest an average hydraulic aperture on the order of 0.02 cm. Data at lower elevations shows that preferential flow occurred over a variety of scales. Some fractures below the infiltration site were completely bypassed, while others showed uneven occurrences of tracer within the fracture plane. Extent of the rock mass that was penetrated by the infiltration pulse is unknown. Lateral migration of fluid outside of the mapped prism appears to have resulted from pressure-driven flow along sub-horizontal fractures dipping gently to the north and east. Fluid also traveled below the mapped prism along persistent near-vertical fractures. The complex and dynamic flow structure formed during this test would have frustrated conventional monitoring strategies that integrate over small areas, or require large integration times.

Previous performance assessment calculations in various countries assumed that only a limited area of a fracture surface provides access to the rock matrix, although an alteration halo that could enhance accessibility often develops along the whole fracture face. We are conducting a set of laboratory experiments to investigate diffusion in and between fracture fillings and matrix using Cretaceous granodiorite from the Kamaishi experimental site in the northern part of the main island of Japan. Three zones have been classified in the granodiorite: 1) fractured areas filled with either recrystallized calcite-based materials or gouge, 2) altered zones characterized by microfractures, and 3) unaltered granodiorite. It is hypothesized that each zone has different diffusion properties. We are testing this hypothesis using x-ray absorption imaging to visualize and quantify diffusion rates in a variety of samples from the different granodiorite zones. Each rock sample is first saturated with an iodide solution. A constant iodide-free concentration boundary is then set on one end of the sample allowing for diffusion out of the specimens. X-ray images are taken at different times during the experiment to measure the relative iodide concentration as a function of time and two-dimensional space at a sub-millimeter spatial resolution. In addition, two-dimensional heterogeneous porosity fields (at the same resolution as the relative concentration fields) are measured using x-ray absorption imaging for each rock sample. This imaging technique allows for a greater understanding of the spatial variability of diffusion rates than can accomplished with standard bulk measurements. Preliminary results indicate faster diffusion rates along the fractures and altered material. Results from the experiments will be used to further develop a conceptual model of transport through the granodiorite. Of particular interest is whether diffusion within the fracture filling material can increase the surface area available for diffusion into the rock matrix and the rate of diffusion.

Injections were performed in sandstone and shale formations at depths of 830 and 595 m, respectively. Typical injection disposal was simulated using multiple small-volume injections over a three-day period, with long shut-in periods between the injections. Microseismic monitoring was achieved using a 5-level array of wall-locked, wireline-run, triaxial-accelerometer receivers in a monitor well 76 m from the disposal well. Results of the mapped microseismic locations showed that the disposal domain was generally aligned with the maximum horizontal stress, with some variations in azimuth, and that wide variations in height and length growth occurred with continued injections. These experiments show that the cuttings injection process can be adequately monitored from a downhole, wireline-run receiver array, thus providing process control and environmental assurance.

The objective of the in situ stress measurements was to define magnitudes and directions of the principal in situ stresses for the design and performance assessment of the future high level nuclear waste repository site. The vertical stress, sigma (sub v) , was estimated from the weight of the volcanic tuff overlying the test-hole to be 4.7 MPa. The hydraulic fracturing tests yield two principal horizontal stresses as follows: sigma (sub h) = 1.7 (+ or -0.1) MPa acting at N75 degrees W (+ or -14 degrees ); sigma (sub H) = 2.9 (+ or -0.4) MPa acting at N15 degrees E (+ or -14 degrees ). The measured stress regime reveals that both horizontal stresses are clearly smaller than the vertical stress, suggesting normal faulting stress regime. This inference is supported by the local predominance of generally N-S trending normal faults related to the Basin and Range Province. Stress indicators such as fault slip and earthquake focal mechanism data around Yucca Mountain also indicate normal faulting stress regime with the minimum horizontal stress generally oriented at E-W.

Welded tuff was taken from Alcove 5 of the Exploratory Studies Facility at Yucca Mountain, and nonwelded tuffs from four lithostratigraphic units were obtained from the USW SD-7, USW SD-9, and USW SD-12 drillholes. Thermal conductivities were measured for six welded and six nonwelded specimens under dry, saturated, and approximately ten intermediate moisture conditions. All thermal conductivity tests were conducted at 30 degrees C and at atmospheric pressure. A linear and commonly used nonlinear curve were fitted to the data and the goodness of fit determined. The linear relationship provides a better fit to the data, as indicated by the sum of the squared errors.

The first of these tests utilized a single heater to elevate the temperature of a 13 m wide, 5.5. m tall, 8.5 m deep block that was exposed on three sides and attached on one side, on the top, and on the bottom. The objective of the work described here was to assess changes in thermal and mechanical properties of intact rock occurring as a result of conducting this in situ test.

Each sub-array consists of transducers permanently installed in three holes arranged in an "L" shape. By appropriate arrangement of the transducers and selection of transmitter-receiver pairs, an active array was created that would allow the measurement of transmitted signal velocities and amplitudes (for attenuation studies) along 270 paths parallel, perpendicular and tangential to the shaft walls. Installation occurred over a period of about two years beginning in early 1989, with nearly continuous operation since that time. We now have up to eight years of data relating to the time-dependent deformation of in situ salt under well known boundary conditions at various stress levels determined by the three installation depths. Results show changes in elastic wave velocity as function of vertical depth, distance from shaft wall and orientation.

A unique feature of this evaluation is the comparison of two estimates of VOC mass present in the soil gas, pore-water, and solid phases (but not including mass as non-aqueous phase liquid [NAPL] of the vadose zone in 1993. One estimate, 1,800 kg, was obtained from vadose zone transport modeling that incorporated molecular diffusion and volatilization to the atmosphere, but not biotic or chemical processes. The other estimate, 2,120 kg, was obtained from the sum of VOC mass physically removed during soil vapor extraction and an estimate of VOC mass remaining in the vadose zone in 1998, both adjusted to exclude NAPL mass. This comparison indicates that biogeochemical processes were at best slightly important to historical VOC plume development. Some evidence of aerobic degradation of non-chlorinated VOCs and abiotic transformation of 1,1,1-Trichloroethane was identified. Despite potentially amenable site conditions, no evidence was found of cometabolic and anaerobic transformation pathways. Relying principally on soil-gas analytical results, an upper-bound estimate of 21 percent mass reduction due to natural biogeochemical processes was developed. Although available information for the CWL indicates that natural attenuation processes other than volatilization to the atmosphere did not effectively enhance groundwater protection, these processes could be important in significantly reducing groundwater contamination and exposure risks at other sites. More laboratory and field research is required to improve our collective ability to characterize and exploit natural VOC attenuation processes, especially with respect to the combination of relatively thick and dry vadose zones and chlorinated VOCs.

Melting was observed in the highest pressure (approx. 71 + or = 2 GPa) experiments at calculated shock temperatures of 27754 + or = 160 K. This single crossing of the gamma-liquid boundary measured here agrees closely with the gamma-iron melting line determined by Boehler (1993), Saxena et al. (1993), and Jephcoat and Besedlin (1997). This gamma-iron melting curve is approx. 300 degrees C lower than that of Shen et al. (1998b) at 80 GP a.

These parameters include hydrologic and transport properties in the vadose and saturated zones, as well as source-term parameters and infiltration rates. A number of resources were used to define the parameter distributions, primarily those provided in the Retrieval Performance Evaluation Report (Jacobs, 1998). A linear rank regression was performed on the vadose-zone hydrologic parameters given in Khaleel and Freeman (1995) to determine if correlations existed between pairs of parameters. No strong correlations were found among the vadose-zone hydrologic parameters, and it was recommended that these parameters be sampled independently until future data or analyses reveal a strong correlation or functional relationship between parameters. Other distributions for source-term parameters, infiltration rates, and saturated-zone parameters that are required to stochastically analyze the performance of the AX Tank Farm using LHS/PORFLOW were adapted from distributions and values reported in Jacobs (1998) and other literature sources. Discussions pertaining to the geologic conceptualization, vadose-zone modeling, and saturated-zone modeling of the AX Tank Farm are also presented.

TEM studies have shown that sometimes periodically spaced, few to few tens of nanometer-scale channels develop parallel to (001). However, these features have never been reported in any laboratory study of olivine weathering. In this study, we characterized the evolution olivine surface morphology during both abiotic and biotic (using Thiobacillus ferrooxidans) laboratory dissolution experiments (pH 2, 3, 4) using both natural and synthetic fayalite. The natural fayalite comes from Cheyenne Canyon Colorado (AMNH # 10928) and contains a few percent laihunite (olivine structure with ordered ferric iron and vacancies approximately (Fe2+)0.8(Fe3+)0.8SiO4). High-resolution scanning electron microscope (SEM) characterization of reacted samples showed that natural and synthetic olivine from the abiotic experiments were deeply etched. Fayalite grains are often bounded by (100), (010), and (001) surfaces, and these surfaces display extremely different surface roughening patterns in abiotic experiments. Samples dissolved in the presence of metabolically active cells are much less reacted and clearly display submicron-spaced planar etch features bounded by (001). Ferrous iron released by dissolution is oxidized by T. ferrooxidans and then precipitates as aggregates of nanocrystalline goethite on the mineral and cell surfaces. High-resolution transmission electron microscope images demonstrate that the spacing of these channels ranges from <10 nm to submicron and show abundant laihunite in relict olivine regions. The olivine shows a spinoidal-like microstructure, arising from the short range ordering of Fe3+ vacancies. X-ray diffraction analyses reveal that the relative abundance of laihunite is higher in reacted samples, confirming that fayalite is preferentially dissolved over laihunite. As shown by Santelli et al., the rate of dissolution of fayalite is independent of solution oxygen concentration under acidic conditions. Thus, fayalite is not more reactive than ferrifayalite or laihunite due a faster oxidative pathway. Metabolizing cells (oxidizing Fe2+ to Fe3+) or the abiotic addition of ferric iron dramatically decreases the reaction rate. Results show that both surface adsorbed ferric iron and structurally incorporated ferric ions appear to dramatically suppress olivine dissolution rates.

Empirical spatial weighting functions calculated from permeability data sets measured on multiple sample supports AN - 17277020; 4590102 AB - With the aid of linear filter theory we analyze 13,824 permeability measurements to empirically address the question, What does an instrument measure? By measure we mean the sample support or sample volume associated with an instrument, as well as how the instrument spatially weights the heterogeneities comprising that sample support. Although the theoretical aspects of linear filter analysis are well documented, physical data for testing the filtering behavior of an instrument, particularly in the context of porous media flow, are rare to nonexistent. Our exploration makes use of permeability data measured with a minipermeameter on a block of Berea sandstone. Data were collected according to a uniform grid that was resampled with tip seals of increasing size (i.e., increasing sample support). Spatial weighting (filter) functions characterizing the minipermeameter measurements were then calculated directly from the permeability data sets. In this paper we limit our presentation to one of the six rock faces, consisting of 2304 measurements, as the general results for each rock face are similar. We found that the empirical weighting functions are consistent with the basic physics of the minipermeameter measurement. They decay as a nonlinear function of radial distance from the center of the tip seat, consistent with-the divergent flow geometry imposed by the minipermeameter. The magnitude of the weighting function decreases while its breadth increases with increasing tip seal size, reflecting the increasing sample support. We further demonstrate, both empirically and theoretically, that nonadditive properties like permeability are amenable to linear filter analysis under certain limiting conditions (i.e., small variances). Specifically, the weighting function is independent of the power average employed in its calculation (e.g., arithmetic versus harmonic average). Finally, we examine the implications of these results for other instruments commonly employed in hydraulic testing (e.g., slug and pump tests).

The analysers are referred to as analyser A, B and C. A new analyser (C) is evaluated, and its role in the recycling of spent rinse waters in semiconductor manufacturing facilities is assessed. This new model was tested against the latest versions of competing, commercially available total organic carbon analysers. The comparison focused on the response time in terms of flow rate and percent recovery, which describes how accurately the analyser represented the actual concentration of the challenge analyte.

The situation envisaged is the recycling of rinse water used in semiconductor manufacture, sought to reduce either the volume of high-purity water produced in the first place or the storage required for recycled water before it is again put to use. In 1996, assessments of instrument response revealed that the fastest then available was 3 minutes, whereas an industry technical committee had arbitrarily fixed on 30 seconds as appropriate, any longer giving insufficient time to ensure that contaminated water would not reach critical production stages. The methods of total organic carbon determination (conductivity or non-dispersive infra-red absorption) are outlined, and the organics used at defined concentrations employed as challengers in the spiked water are tabled. The instruments used in the earlier investigations and a third, more recent, instrument were augmented by 2 reference instruments, chosen for their accuracy rather than speed of response.

The effects of contact angle, local aperture field geometry, and local in-plane interfacial curvature between phases are included in the calculation of invasion pressure for individual sites in a discretized aperture field. This pressure controls the choice of which site is invaded during the displacement process and hence the growth of phase saturation structure within the fracture. To focus on the influence of local in-plane curvature on phase invasion structure, we formulate a simplified nondimensional pressure equation containing a dimensionless curvature number (C) that weighs the relative importance of in-plane curvature and aperture-induced curvature. Through systematic variation of C, we find in-plane interfacial curvature to greatly affect the phase invasion structure. As C is increased from zero, phase invasion fronts transition from highly complicated (IP results) to macroscopically smooth. In addition, measurements of fracture phase saturations and entrapped cluster statistics (number, maximum size, structural complication) show differential response between wetting and nonwetting invasion with respect to C that is independent of contact angle hysteresis. Comparison to experimental data available at this time substantiates predicted behavior.

In the estimation of transportation risks, population bordering a route is a direct factor in determining consequences and an indirect factor in determining exposure times, accident probabilities and severities, and other parameters. Proposals to transport RAM may draw intense resistance from "stakeholders" based on concern for population concentrations along urban segments but the length of a route segment is also a determinative factor in estimating the transport risks. To quantify the relative importance of these two factors, a potential route for transport of SNF (strict use of Interstate highways) was selected and compared with a modified version that bypassed urban areas. The results suggest that emphasis on Interstate highways minimizes total route and urban segment risks.

White Rock Creek is a perennial gaining stream occupying a catchment underlain by expanding clay soils, and an uppermost fractured bedrock weathering zone (which acts as a surface aquifer) below which there is low permeability Austin Chalk. Seasonal variations in cation export are controlled predominantly by temperature effects on carbonate solubility, dilution by variable amounts of rainfall, and possibly organic activity. Creek water P (sub CO2) is 7 to 10 times atmospheric P (sub CO2) throughout the year, and does not correlate with surface temperature. Non-pyrite sulfate inputs are well-constrained; moreover, integrated runoff and solute export from the basin are similar to global mean values. Pyrite, although present only as a trace component, accounts for a disproportionate amount of bedrock weathering ( approximately 40%) when oxidized to produce sulfuric acid. Irreversible dissolution of pyrite is insensitive to seasonal changes in temperature, runoff, and organic activity and probably reflects the slow movement of a weathering front at depth through the aquifer.

Formate or lactate served as the electron donor and oxidized U(VI) and Mo(VI) species served as electron acceptors. Greater than 99% removal efficiencies were achieved for both metals with initial concentrations of 5 mg/L U and 10 mg/L Mo. Hydraulic residence times in the columns were between 24 and 36 h. Sulfate concentrations as high as 2000 mg/L did not inhibit reduction of U or Mo in the columns. However, nitrate inhibited uranium reduction at concentrations near 50 mg/L and inhibited molybdenum reduction at concentrations near 150 mg/L. The results indicate that enzymatic reduction of U and Mo by immobilized cells of D. desulfuricans may be a practical method for removing these contaminants from solution in continuous-flow reactors.

More specifically, the demonstration compares the performance of four alternative designs specifically geared for drier environments to the performance of two cover designs endorsed by the Environmental Protection Agency (EPA) for nationwide use. For a thorough comparison, data concerning the weather, soil moisture status, surface runoff, lateral drainage, and percolation through the covers must be collected. A complex array of instrumentation is in place to continually collect this data. The system is completely automated.

NSD analyses of heme structures obtained from X-ray crystallography and MM calculations of heme-peptide fragments of the cytochromes c sub(3) indicate that the nonplanarity of the hemes is largely controlled by a fingerprint peptide segment consisting of two heme-linked cysteines, the amino acids between the cysteines, and the proximal histidine ligand. Additional interactions between the heme and the distal histidine ligand and between the heme propionates and the protein also influence the heme conformation, but to a lesser extent than the fingerprint peptide segment. In addition, factors that influence the folding pattern of the fingerprint peptide segment may have an effect on the heme conformation. Large heme structural differences between the baculatum cytochromes c sub(3) and the other proteins are uncovered by the NSD procedure. These heme differences are mainly associated with the deletion of two residues in the covalently linked segment of hemes 4 for the baculatum proteins. Furthermore, some of these structural differences are reflected in the RR spectra. For example, the frequencies of the structure-sensitive lines (v sub(4), v sub(3), and v sub(2)) in the high-frequency region of the RR spectra are lower for the Desulfomicrobium baculatum cytochromes c sub(3) (Norway 4 and 9974) than for the Desulfovibrio (D.) gigas, D. vulgaris, and D. desulfuricans strains, consistent with a more ruffled heme. Spectral decompositions of the v sub(3) and v sub(10) lines allow the assignment of the sublines to individual hemes and show that ruffling, not saddling, is the dominant factor influencing the frequencies of the structure-sensitive Raman lines. The distinctive spectra of the baculatum strains investigated are a consequence of hemes 2 and 4 being more ruffled than is typical of the other proteins.

We begin with an overview of the effects of microbial activity on the chemical dynamics in these environments. Then, after a review of earlier modeling efforts, we introduce a one-dimensional, multi-component reactive transport model that accounts for the reaction couplings among the major redox and acid-base elements, O, C, H, N, S, Mn, Fe and Ca. The model incorporates kinetic descriptions for the microbial degradation pathways of organic matter, as well as for the secondary redox reactions and mineral precipitation-dissolution reactions. Local equilibrium only applies to fast homogeneous speciation reactions and sorption processes. The model is used to simulate the distributions of chemical species and reaction rates along flow paths in two subsurface environments. In the first case, waters containing moderate levels of natural soil-derived organics supply a regional groundwater system. In the second case, a pristine aquifer is contaminated by an organic-rich leachate from a landfill. In both environments, the microbial oxidation of organic matter causes the disappearance of dissolved and solid oxidants and the appearance of reduced species, albeit over very different spatial scales. In the second case, a pronounced reaction front develops at the downstream edge of the contaminant plume. The reactivity, or biodegradability, of the organic matter is shown to be a major factor governing the biogeochemical dynamics in the plume. The simulations predict different distributions of the biodegradation pathways, depending on whether the organics of the leachate have uniform or variable reactivity. The secondary reactions also have a significant impact on the concentration profiles of inorganic species and the spatial distributions of the biodegradation pathways. Within the downstream reaction front, large fractions of O (sub 2) , Mn(IV), Fe(III) and SO (super 2-) (sub 4) are reduced by secondary reactions, rather than being utilized in the oxidative degradation of leachate organics. Overall, the model simulations emphasize the strong coupling between subsurface heterotrophic activity and an extensive network of secondary reactions.

Exchange of Al for protons and hydroxyls is observed at low pH, with a stoichiometry approaching 1:3 (Al:H (super +) ). Adsorption of organic acids from dilute solutions depends on: 1) solution pH; 2) the functionality of the acid; and, to a lesser extent, 3) temperature. Such adsorption may occur primarily at Al sites exposed on kaolinite edges, as indicated by sorption experiments on the constituent oxides, where negligible sorption was observed on SiO (sub 2) (quartz), but was significant on Al (sub 2) O (sub 3) (corundum) surfaces. Under similar conditions, oxalate adsorbs more strongly than acetate or formate to aluminol sites.

We want to know the importance of high-frequency (>16 Hz) seismic data in identifying these explosions. The deployable seismic verification system (DSVS) in Wyoming records data up to 50 Hz with good signal to noise, so it is an excellent source for determining the benefits of recording data over 16 Hz. We developed a database of 118 known earthquakes and 176 known ripple-fired explosions. We calculated a binary spectrogram and an average binary spectrum for each event and developed criteria based on the number of peaks and nulls above certain thresholds to classify events as ripple-fired explosions. Using data at frequencies up to 50 Hz, 50% of the known ripple-fired explosions were correctly identified, and another 22% had banding in the spectrogram but did not meet the established criteria. The other 27% of the known ripple-fired explosions had no banding. To test the importance of high-frequency (>16 Hz) data, we recalculated spectrograms between 0 and 16 Hz for the 135 known ripple-fired explosions and earthquakes that had banding. Eleven of the 135 could not be identified correctly if data over 16 Hz was excluded; 5 had information at frequencies over 16 Hz that was critical to seeing any banding. But the vast majority of events were correctly identified in the pass band of 0 to 16 Hz, suggesting that higher-frequency data do not significantly help to identify most ripple-fired explosions in Wyoming.

Using self- and tracer-diffusion coefficients obtained from laboratory experiments on natural calcite, cooling rates are calculated for various temperatures and diffusion distances to assist in the evaluation of the compositional zoning associated with the carbonate phases in ALH 84001. The closure temperature model provides the average temperature below which compositional zoning will be preserved for a given cooling rate, that is, the temperature at which diffusion will be ineffective in homogenizing the phase. The validity of various theories for the formation of the carbonate globules may be examined, therefore, in view of the diffusion-limited kinetic constraints. Experiments using a thin film-mineral diffusion couple and ion microprobe for depth profiling analysis were performed for the temperature range of 550-800 degrees C to determine self-and tracer-diffusion coefficients for Ca and Mg and in calcite. The resulting activation energies for Ca (E (sub a) (Ca) = 271 + or - 80 kj/mol) and for Mg (E (sub a) (Mg) = 284 + or - 74 kj/mol) were used then to calculate a series of cooling rate, grain size, and closure temperature curves. The data indicate, for example, that by the diffusion of Mg in calcite, 1 10 2m compositional zone would be completely homogenized at a temperature of 300 degrees C for cooling rates (sub 100K/Ma. These data provide no constraint on formation models that propose a low-temperature fluid precipitation mechanism; however, they indicate that the carbonate globules were not exposed to a high-temperature environment for long time scales following formation.

The ultimate objective was to determine which of several geostatistical inverse techniques is better suited for making probabilistic forecasts of the potential transport of solutes in an aquifer where spatial variability and uncertainty in hydrogeologic properties are significant. Seven geostatistical methods (fast Fourier transform (FF), fractal simulation (FS), linearized cokriging (LC), linearized semianalytical (LS), maximum likelihood (ML), pilot point (PP), and sequential self-calibration (SS)) were compared on four synthetic data sets. Each data set had specific features meeting (or not) classical assumptions about stationarity, amenability to a geostatistical description, etc. The comparison of the outcome of the methods is based on the prediction of travel times and travel paths taken by conservative solutes migrating in the aquifer for a distance of 5 km. Four of the methods, LS, ML, PP, and SS, were identified as being approximately equivalent for the specific problems considered. The magnitude of the variance of the transmissivity fields, which went as high as 10 times the generally accepted range for linearized approaches, was not a problem for the linearized methods when applied to stationary fields; that is, their inverse solutions and travel time predictions were as accurate as those of the nonlinear methods. Nonstationarity of the "true" transmissivity field, or the presence of "anomalies" such as high-permeability fracture zones was, however, more of a problem for the linearized methods. The importance of the proper selection of the semivariogram of the log (sub 10) (T) field (or the ability of the method to optimize this variogram iteratively) was found to have a significant impact on the accuracy and precision of the travel time predictions. Use of additional transient information from pumping tests did not result in major changes in the outcome. While the methods differ in their underlying theory, and the codes developed to implement the theories were limited to varying degrees, the most important factor for achieving a successful solution was the time and experience devoted by the user of the method.

The model exploits the wave-like propagation of the evaporation fronts of individual species to present analytical expressions for the in-situ compositions, contaminant volumes, effluent concentrations, and recovery rates during discrete time intervals. The efficiency of soil vapor extraction systems also can be determined. Comparison of this theory to a previous experiment of through-flow venting of benzene, toluene, and o-xylene yielded excellent agreement. This suggests that if effluent concentrations of individual species are monitored in the field during soil vapor extraction operations, only minimal data are required at early times to yield predictions of in-situ compositions and contaminant volumes, as well as subsequent effluent concentrations and recovery rates.

Velocity model building and updates use an image-driven strategy and were performed in a Sun Sparc environment. Images obtained by 3-D prestack migration after three velocity iterations are substantially better focused and reveal drilling targets that were not visible in images obtained from conventional 3-D poststack time migration. Amplitudes are well preserved, so anomalies associated with known reservoirs conform to the petrophysical predictions. Prototype development was on an 8-node Intel iPSC860 computer; the production version was run on an 1824-node Intel Paragon computer. The code has been successfully ported to CRAY (T3D) and Unix workstation (PVM) environments.

Unfortunately, the high degree of cultural noise in developed oil fields has limited the use of surface electrical techniques, and the preponderance of steel well casings has limited the deployment of borehole tools in completed wells. The result is that, with the exception of open-hole logging, electrical methods are not routinely used in oil fields after the exploration phase is complete.

Efficient and objective parameter estimation is obtained through inverse modeling techniques. The examples demonstrate the sensitivity of the estimated geohydrologic parameter values within the geohydrologic units to variations in spatial distribution of those units. In all three examples, geological information in the form of stratigraphic opinion or geophysical interpretation regarding unit distributions, as a well as geologic rules ranking hydraulic conductivity of units, improves conceptual model development.

The amount of lateral diversion above the coarse layer under steady state infiltration conditions is compared among the simulations. Results indicate that the performance of capillary barriers can be significantly influenced by the spatial variability of hydraulic properties. In the layered heterogeneous systems, realizations with highly stratified regions within the fine layer performed best and resulted in localized capillary barriers that delayed breakthrough into the coarse layer. In contrast, realizations of the random heterogeneous system performed worst because of channeled flow that produced numerous localized regions of breakthrough into the coarse layer. Results of the homogeneous model were comparable to the mean results of the layered heterogeneous realizations, but homogeneous results underpredicted the frequency and amount of breakthrough for all realizations of the random heterogeneous system. These results indicate that homogeneous models can be used to estimate the average behavior of layered heterogeneous systems with reasonable accuracy. In addition, engineered capillary barriers may be improved through emplacement and packing methods that induce highly stratified features within the fine layer of a capillary barrier system.

An important design consideration in the development of supercritical water oxidation is the optimization of reactor operating temperature and feed preheat temperatures. In this paper, the temperature dependence of the oxidation in supercritical water of seven common organic compounds is examined over a temperature range of 430-585 degree C and reaction times ranging from 7 to 30 s at 27.6 MPa (4000 psi). The reactants are examined at approximate concentrations of 0.4 wt.% at conversion efficiencies from 50% to > 99.9%. The materials examined were methanol, phenol, methyl ethyl ketone, ethylene glycol, acetic acid, methylene chloride, and 1,1,1-trichloroethane. The conversion of these compounds was monitored using total organic carbon and gas chromatography on liquid effluent samples. The results indicate that for most compounds, temperatures over 550 degree C and residence times near 20 s afford conversion efficiencies of greater than 99.95% based on total organic carbon.

An analysis is presented of possible radiation exposures associated with inadvertent drilling intrusions through the WIPP using future drilling rates obtained in accordance with requirements specified by the U.S. Environmental Protection Agency (EPA) in 40 CFR 194, Subpart B. The analysis attempts to maintain a separation between stochastic (i.e., aleatory) and subjective (i.e., epistemic) uncertainty as implied in the EPA regulations 40 CFR 191, Subpart B, and 40 CFR 194. The results of the analysis are presented as distributions of complementary cumulative distribution functions (CCDFs) for radiation exposure to oil field workers, where the individual CCDFs arise from stochastic uncertainty (i.e., many possible patterns of drilling intrusions are possible over the 10,000 yr period specified in 40 CFR 191, Subpart B) and the distributions of CCDFs arise from subjective uncertainty (i.e., many inputs to the analysis have fixed, but poorly known, values). The projected radiation exposures during the 10,000 yr period following decommissioning of the WIPP in the year 2033 were found to be small (typically less than 0.001 person-Sv), with the dominant exposure pathway being the incidental ingestion of contaminated dirt by drilling crew members.

Here we experimentally identify and classify potential sorbent materials for inclusion in LLRW backfills. For low pH conditions (pH 4-5), Cu-sulfides and possibly imogolite-rich soils provide K (sub d) 's (distribution coefficients) of roughly 10 (super 3) mL g (super -1) for I (super -) , and 102 mL g (super -1) for TcO (super -) (sub 4) .

A natural rock fracture was collected from the field and prepared for study. Silicon rubber molds of the fracture surfaces were used to make a transparent epoxy replica of the original fracture. Clear and dyed water were injected into the fracture pore space allowing examination of the flow field. Digitized optical images were used to observe wetting, saturated flow, and drying of the specimen. Nuclear magnetic resonance imaging was used for quantitative measurements of flow velocity. Both video imaging and nuclear magnetic resonance imaging techniques show distinct and strong channeling of the flow at the submillimeter to several-centimeter scale. Each phenomenon, including wetting, drying, dye transport, and velocity channeling, has its own distinct geometric structure and scale. We find that fluid velocities measured simultaneously at various locations in the fracture plane during steady state flow range over several orders of magnitude, with the maximum velocity a factor of 5 higher than the mean velocity. This suggests that flow channeling in fractured rock can cause the breakthrough velocity of contaminants to far exceed the mean flow. Copyright 1998 by the American Geophysical Union.

We address how the true voxel-scale attenuation distribution and measurement errors are convoluted to yield measured density frequency distributions. A deconvolution algorithm is demonstrated that uses the measured density frequency distributions and known photon statistical errors to quantify average cross-section volume contents of pure components and a mixed-component phase. The mixed-component phase represents regions where components are intertwined or varied in spaces smaller than the scanning resolution. This approach is applied to a complex core of the Culebra Dolomite Member of the Rustler Formation collected at the Waste Isolation Pilot Plant, near Carlsbad, New Mexico. The methodology provides a quantitative measure of the volume content of gypsum, dolomite, and mixed-components, and heterogeneity in the sample. Copyright 1998 by the American Geophysical Union.

In the present era of inexpensive digital storage, however, such algorithms are increasingly being used to flag signal segments in continuously recorded digital data streams for subsequent processing by automatic and/or expert interpretation systems. In the course of our development of an automated, near-real-time, waveform correlation event-detection and location system (WCEDS), we have surveyed the abilities of such algorithms to enhance seismic phase arrivals in teleseismic data streams. Specifically, we have considered envelopes generated by energy transient (STA/LTA), Z-statistic, frequency transient, and polarization algorithms. The WCEDS system requires a set of input data streams that have a smooth, low-amplitude response to background noise and seismic coda and that contain peaks at times corresponding to phase arrivals. The algorithm used to generate these input streams from raw seismograms must perform well under a wide range of source, path, receiver, and noise scenarios. Present computational capabilities allow the application of considerably more robust algorithms than have been historically used in real time. However, highly complex calculations can still be computationally prohibitive for current workstations when the number of data streams become large. While no algorithm was clearly optimal under all source, receiver, path, and noise conditions tested, an STA/LTA algorithm incorporating adaptive window lengths controlled by nonstationary seismogram spectral characteristics was found to provide an output that best met the requirements of a global correlation-based event-detection and location system.

Diffusion of (super 25) Mg was induced in polished samples via a film of isotopically enriched (super 25) Mg as the source material. The diffusion coefficients for 900, 850, 800 and 750 degrees C provide the activation energies (E (sub a) ) and frequency factors (D (sub o) ) where D = D (sub o) exp (-E (sub a) /RT) for Mg self-diffusion each crystallographic direction: a-axis, E (sub a) 360 + or - 52 Kj/mole and D (sub o) 1.10 X 10 (super -4) m (super 2) /s; b-axis, E (sub a) 339 + or - 77 kJ/mole and D (sub o) 6.93 X 10 (super -6) m (super 2) /s; c-axis, E (sub a) 265 + or - 66 kJ/mole and D (sub o) 4.34 X 10 (super -9) m (super 2) /s. Application of these results to silicates in the Lowicz mesosiderite meteorite provides cooling rates of 4-11 degrees C/100 yr for the silicate portion of this meteorite; these cooling rates are several orders of magnitude faster than those (0.1 degrees C/m.y.) for the metal portions.

AN - 79823051; 9565467 AB - Intact cells of Desulfovibrio desulfuricans, immobilized in polyacrylamide gel, removed Cr, Mo, Se and U from solution by enzymatic-mediated reduction reactions. Lactate or H2 served as the electron donor and the oxidized Cr(VI), Mo(VI), Se(VI) and U(VI) served as electron acceptors. Reduction of the oxidized metal species resulted in the precipitation of solid phases of the metals. Metal removal efficiencies of 86-96% were achieved for initial concentrations of 1 mM Mo, Se, and U and 0.5 mM Cr. Insoluble metal phases accumulated on both the surface and the interior of the polyacrylamide gel. In column tests conducted for U removal, effluent concentrations less than 20 micrograms L(-1) were achieved with initial concentrations of 5 mg L(-1) and 20 mg L(-1) U and residence times from 25-37 h.

From visual sightings, it is concluded that the object wasn't a meteoric fireball (bolide). A surface "crater" in Cando (close to Santiago) with dimensions 29X13 m and 1.5 m deep was later discovered within 1 km of the projected "impact" point of the luminous object. At this site, in addition to the topsoil, full-grown pine trees >20 m high were thrown downhill over a nearby road, leaving the downslope edge of the "crater" untouched and with a steep interior wall (this would not be the case if a regular landslide were responsible for the transport). Standing trees below the "crater" showed embedded soil and plant residues up to heights >3 m. No strange materials (meteorites or artifacts) were recovered in or close to the "crater"; all materials belonged to the site and were not shocked; thus, an impact is very improbable. A possible explanation capable of reconciling all of the observations is presented. It hypothesizes an eruption of earth gases to create the crater, with the rising gas plume then interacting with atmospheric electricity to produce the propagating fireball that was observed.

From multiple well interference testing a strong permeability anisotropy was found. Reservoir simulations were performed in two pilot areas of different fracture intensity to quantify the potential for infill drilling, reducing the well spacing from 320 to 160 acre. Simulation results indicate areas of effective drainage, the optimum locations for infill wells, and the additional recovery from infill wells.

A systematic study of fracture characteristics and variability was undertaken in an attempt to develop a model describing fracturing associated with basement-cored anticlines in the Rocky Mountain region. Most field measurements were taken from strata within the Cretaceous Mesaverde Group. Variability of fracture patterns was found related to both structural position and lithology.

Before this acquisition occurred the data for fracture characterization was ambiguous. The orientation has been investigated through use of tracer surveys, pulse testing, and production monitoring, and generally found to be along a NE to SW trend that could vary as much as 20 to 40 degrees. There are those whom believed that the existence of natural fractures was not significant enough and should not be a key part of reservoir characterization. The acquisition of the core unequivocally documents numerous, closely spaced natural fractures in the reservoir rock of the Spraberry formation.

The outcrop study, combined with 2-D seismic and well data, suggests that both fault and fracture formation are penecontemporaneous with fold formation.Teapot Dome is an asymmetric, doubly plunging, Laramide anticline with a fold hinge that is curved in map view. A basement-involved thrust is evident in 2-D seismic data at the core of the anticline. NE-striking normal oblique faults, predominately perpendicular to the curvilinear fold hinge, are common along the eastern limb. More than 90% of these faults terminate before intersecting the western limb; displacements therefore decrease to the SW. Two main through-going fracture sets have been documented: 1) Bed-normal extension fractures trending parallel to the fold hinge are found throughout the fold. 2) Bed-normal extension fractures trending subparallel to the NE-striking normal oblique faults. The latter fracture set is best developed along the eastern limb where normal faults are common. The hinge-parallel fractures are younger than the fault-related fractures where the relative ages of the two fracture sets can be established. Fracturing and normal faulting are broadly contemporaneous with basement-involved thrusting and folding at Teapot Dome as suggested by observations that A) fault-related fractures are generally older than hinge-parallel fractures, B) normal faults are oriented roughly perpendicular to the fold hinge, even where it bends, and C) normal faults terminate toward the SW limb of the anticline.

Geostatistical simulation techniques can be applied to existing data to map the probability of exceeding a regulatory threshold (action level) across the site. This probability map can be used to devise a remediation plan based on an allowable probability of exceeding the regulatory action level that is acceptable to regulators and stakeholders. Compared with the traditional, deterministic approach to defining areas to be remediated, this probabilistic approach requires an acknowledgment of a nonzero probability of failure (failing to remove material actually exceeding the action level) that must be agreed upon by the regulators and stakeholders. Evaluation of costs for remediation alternatives and for potential regulatory failure can be combined with probability maps to provide site operators, regulators and stakeholders with cost-risk information from which key decisions can be effectively understood and negotiated. Approximately 300 samples were collected from a site in central New Mexico. These samples show concentrations of lead ranging from the 0.1 to 3,000 ppm. Initial negotiations with stakeholders and regulators resulted in two action levels being considered where each action level defined an acceptable human health risk for a residential or a industrial future land-use scenario. Probability-of-exceedence maps were created through geostatistical simulation at both action levels. Maps of areas to be remediated for several acceptable probabilities of exceedence, and the corresponding remediation costs as a function of proposed action level allowed the regulators and stakeholders to see clearly the economic consequences of their decisions. In the final decision, the regulators and stakeholders accepted a higher action level and a remediation map constructed with a five percent probability of exceedence. The cost difference between the selected action level, corresponding to an industrial future land-use scenario, and the alternative action level, corresponding to a residential future land-use scenario resulted in a projected savings in remediation costs of approximately $6.6 million.

The application of geoscience to these ends, especially engineering geology, has occurred from pole to pole and included every conceivable environment and natural condition. In the conduct of such projects, the geosciences have advanced, and vice versa. Desert trafficability, most notably regarding playa surfaces, is temporary and variable and not a persistent condition as some early authors believed. Playas in Australia, Iran, and the United States show that saline efflorescence is removed following surface water dissolution and subsequent deflation, resulting in very hard crusts. Magadiite, a hydrous sodium silicate and possible precursor of bedded chert, was first discovered in North America at Alkali Lake, Oregon, during a military project. Pleistocene Lake Trinity, a small and mostly buried evaporite basin in the northern Jornada del Muerto, New Mexico, was discovered during exploratory drilling in support of a military test program. The Strategic Petroleum Reserve (SPR), operated by the U.S. Department of Energy, has underground cavern storage of approximately 600 million barrels of crude oil in five Gulf Coast salt domes. The geologic characterization of the SPR sites is a major component of these comprehensive engineered works--unparalleled in modern times and on a comparable scale with the Panama Canal. Numerous studies of salt-stock heterogeneity, salt-karst features, and structural and physical attributes of salt deposits are broadening the database for use in the commercial storage industry. Geologists serving in military and national security endeavors are fully functioning members of the project technical teams and have made significant advances to the geosciences.

They range from a hectare or less to hundreds of square kilometers, and they may support aircraft landings or be totally impassable to land vehicles. Because they possess distinctive physical attributes and are common elements of arid and semiarid landscapes, which occupy nearly 30% of the Earth"s land surface, they have had significant effects on military history and operations for centuries. This significance is not apt to diminish. The single most important determinant of playa-surface conditions is the combination of surface and ground-water hydrology. Playas with ground water that is sufficiently deep to preclude capillary rise favor hard surface crusts. Prolonged capillary or direct ground-water discharge in arid environments readily builds up evaporite mineral assemblages including halite, gypsum, and calcite. Changing hydrologic conditions resulting either naturally or from human activity, for example, ground-water extraction, can result in alteration of relief and surface hardness of playas over both short- and longer-time spans. Military use by ground forces includes both expeditious and evasive maneuvering of ground vehicles. Air and spaceborne vehicles, including fixed and rotary wing craft and spacecraft, have used numerous playas in their natural state as landing platforms, and many other playas are readily available in remote, unpopulated areas of the globe. Future uses are apt to take advantage of the unique attributes of this arid-region feature--the flattest of all landforms.

The extremities of the arctic environment demanded unique adaptations to normal military operations, which provided military and engineering geologists an opportunity to exercise a broad range of technical applications. New knowledge and skills in ice physics and engineering, glaciology, arctic geomorphology, meteorology, oceanography, and permafrost engineering were all relevant, often requiring on-the-job learning. Such adaptability could be needed in the future and would once again challenge military geologists.

The (super 29) Si spectra were recorded using direct polarization, MAS and variable delay time in a saturation recovery pulse sequence. Resonances observed at -97.3, -107.1, -113.9 and -191.2 ppm were assigned to a densified hydrous form of amorphous silica (D phase), quartz, coesite and stishovite phases, respectively, with relative percentages estimated at 1.7, 80.6, 16.4 and 1.3% for these phases. The power-law recoveries of the magnetization for the quartz and coesite can be interpreted in terms of their phase geometries.

The process was created when Sandia realized that standard engineering practices did not provide the level of safety assurance necessary for nuclear weapon operations, with their potential for catastrophic accidents. A systematic approach, which relies on mutually supportive design principles integrated through fundamental physical principles, was developed to ensure a predictably safe system response under a variety of operational and accident-based stresses. Robust, safe system designs result from this thematic approach to safety, minimizing the number of safety critical features. This safety assurance process has two profound benefits: the process avoids the need to understand or limit the ultimate intensity of off-normal environments and it avoids the requirement to analyze and test a large array of accident environment scenarios (e.g., directional threats, sequencing of environments, time races, etc.) to demonstrate conformance to all safety requirements.

Ocean location is shown to strongly influence collision frequencies but to have little effect on fire frequencies, which depend principally on trip duration. Because collisions always involve at least two ships, collision frequencies increase as ship traffic increases. Collision frequencies are developed for 19 high traffic ocean regions, for all coastal waters not in these 19 regions, and for the open ocean. Collision frequencies in high traffic ocean regions are one to two orders of magnitude larger than collision frequencies in the open ocean. The frequencies of collisions per port call are developed for high, medium, and low traffic ports. Values for the frequency of fires per nautical mile sailed and per port call are also developed.

As with other modes, a sea-going conveyance (vessel) carrying radioactive material (RAM) may be involved in a collision accident. If the vessel is struck by another commercial vessel with sufficient tonnage and velocity, the RAM package may be impacted by the penetrating bow of the striking ship. The impact on the RAM package by the bow is less damaging to the package than the regulatory 9 m drop test. This is because the velocity is always lower and the bow always less rigid than the essentially unyielding target required for the drop test. Thus, the only remaining mechanism for gross damage to the package is crush loading. For the package to be crushed, forces must act on two opposing sides. In this paper, the bow of the impacting ship is assumed to be able to impart an infinite force to one side of the package. The opposing force is supplied by the hull of the struck ship on the side away from the collision. Resistance of this hull to penetration by the package determines the maximum magnitude of the crush force. Work described in this paper is aimed at determining an upper bound for this force.

The experiments, conducted aboard an actual break-bulk cargo ship, simulate conditions for both fires in adjacent ship holds and for cargo fires in the same hold with the hazardous cargo. Following a description of the experimental arrangement, typical results are presented, and then compared with results from computational fluid dynamics simulations. Comparisons between the shipboard fire environment and land based fires are discussed, and conclusions regarding shipboard fires and their simulation are drawn.

Before disposal, MLLW is usually treated to comply with the land disposal restrictions of the Resource Conservation and Recovery Act. Depending on treatment type, the volumes and radionuclide concentrations of the waste streams may change. These changes must be taken into account in determining necessary disposal capacity at a site. Treatment may remove the characteristic feature that caused classification as mixed waste. Treatment may also, by reduction of mass, increase the concentrations of transuranic radionuclides sufficiently so that some waste becomes transuranic waste. This paper describes an analysis of the DOE MLLW streams to determine treated volumes and radionuclide concentrations. The waste streams were reclassified as residual MLLW, or low-level or transuranic waste resulting from treatment. About 89,000 m super(3) of waste was identified for disposal as residual MLLW. Fifteen DOE sites were evaluated to determine their capabilities for hosting disposal facilities for residual MLLW. Waste streams associated with about 90% of the residual MLLW volume are likely to present no significant issues for disposal. Future studies should focus on the remaining waste streams that are potentially problematic by examining site-specific waste acceptance criteria, alternative treatment processes, alternative waste forms for disposal, and pending changes in regulatory requirements.

Transport was shown to occur in three distinct regimes: fracture, dualporosity and total porosity transport. In the fracture transport regime, contaminant transport is controlled by fracture porosity alone. This was shown to end too quickly to have any significance for nuclear waste repositories like the Waste Isolation Pilot Plant (WIPP). Dual-porosity transport, in which contaminants are predominantly inside the matrix porosity and in the process of diffusing deeper into the rock, was shown to be controlled by a single formation parameter, called here the transport length, which can be estimated from tracer tests. Although conventional two-well tracer tests yield ambiguous values for fracture width and porosity, they provide useable estimates of the transport length. The effect on tracer tests of random heterogeneity and anisotropy in the formation was analyzed; the arithmetic mean of inferred values from different tests is the correct average for the transport length and the harmonic mean is the correct average for the kinematic porosity. Data were analyzed from nine tracer tests in a dual-porosity dolomite in the Culebra formation above the WIPP repository, including one test repeated at a different flow rate. The effect of dual-porosity on the mean transport rate of contaminants potentially leaking from the WIPP repository was shown to be negligible. Thus, for off-site transport at the WIPP, the formation is adequately modeled as a single-porosity, matrix-only medium.

Two data sets were examined which contained trichloroethylene, 1,1,2-trichloroethane, toluene and chloroform. The second data set also contained tetrachloroethene. Both algorithms performed comparably on a given data set. The quantitative performance for modelling toluene and chloroform decreased upon the addition of tetrachloroethene due to an overlap of absorption features.

The most likely contaminant would be organic carbon of one family or another. Suggestions for the specification to be met for a total organic carbon analyser for use in such a situation are offered. A prime requirement would be for a rapid response time; present instruments required 180-240 seconds but 30 seconds was the permissible maximum. To achieve this, a relaxed detection limit of 30 ppb, as distinct from the 10 ppb detectable by instruments that took longer, is proposed. The instrument should also be able to respond to as many as possible of the individual organics within a family. Test solutions should be prepared so that after dilution with recycled water it reached a concentration of 100 ppb at the analyser.

The method that should be used to analyse radionuclide transport through groundwater to achieve conservative dose estimates at the exposure point is shown for each category. For those radionuclides (including uranium-235 which had a dose value 16.4 times greater at 10,000 years than at 100 years) for which the simplified 'transport then decay' analysis could underestimate the dose from release into the shallow subsurface and transport through the environment, an alternative approach that ensured conservatism is presented. This approach is illustrated by calculating the maximal annual effective dose equivalents from drinking water containing the radionuclides concerned over a 10,000 year period of analysis. The proposed method could be incorporated into groundwater transport models for risk or performance assessment.

Biosolids supply both organic matter and available nutrients that are lacking in degraded rangeland soils. This study investigated the effects of biosolids applications of 0, 22.5, 45, and 90 Mg ha (super -1) to a degraded rangeland in 1985 on the soil chemical properties and N mineralization potentials 8 and 9 yr after the application, respectively. Following an initial increase in proportion to the application rate, levels of water-extractable Ca, Mg, Na, nitrate (NO (sub 3) -N), and electrical conductivity declined to that near the control soils after 8 yr. Nearly all diethylenetriaminepentaacetic acid (DTPA)-extractable metals (Fe, Zn, Cu, Cd, and Pb) were highest in the collection 4 yr after application, but were near concentrations in the control soil after 8 yr. Nitrogen mineralization potentials were significantly higher (P <0.05) in the 45 and 90 Mg ha (super -1) applications after 9 yr, indicating that site fertility remained higher even though most soil chemical properties were returning to untreated levels.

EM640(t) AN - 51908174; 2004-001695 AB - The Bruker-Franzen EM640 GC/MS consists of a temperature-programmable gas chromatograph coupled to a mass spectrometer. The field transportable system used a small gas chromatographic column and accompanying mass spectrometer to provide separation, identification, and quantification of volatile and semi- volatile organic compounds in soils, liquids, and gases. In the demonstration, the system used a spray-and-trap technique for water analysis, as well as direct injection and head space analysis for soil gas and soil analyses, respectively. The column enables separation of individual analytes in complex mixtures. As these individual analytes exit the column, the mass spectrometer detects the analytes, providing a characteristic mass spectrum that identifies each compound. An external computer system provides quantitation by comparison of detector response with a calibration table constructed from standards of known concentration. The system provides very low detection limits for a wide range of volatile and semi-volatile organic contaminants.

The WIPP disposal facility is located approximately 2,150 feet (650 m) below surface in the bedded halite of the Salado Formation. Prior to initiation of disposal activities, the Department of Energy must demonstrate that the WIPP will comply with all regulatory requirements. Applicable regulations require that contaminant releases from the WIPP remain below specified levels for a period of 10,000 years. To demonstrate that the WIPP will comply with these regulations, the Department of Energy has requested that Sandia National Laboratories develop and implement a comprehensive performance assessment of the WIPP repository for the regulatory period. This document presents the conceptual model of the shaft sealing system to be implemented in performance assessment calculations conducted in support of the Compliance Certification Application for the WIPP. The model was developed for use in repository-scale calculations and includes the seal system geometry and materials to be used in grid development as well as all parameters needed to describe the seal materials. These calculations predict the hydrologic behavior of the system. Hence conceptual model development is limited to those processes that could impact the fluid flow through the seal system.

The droplets are assumed to exist near asperities and cavities as a result of gravity-dominated flow through fractures. Because of the curvature of the droplet, the vapor pressure near the liquid-vapor interface is greater than the saturated vapor pressure of water held in the matrix at the system temperature. Expressions for the vapor pressure and evaporation rate of water droplets are developed as a function of droplet radius and relative humidity of the surroundings. The relative humidity is calculated using Kelvin's equation to account for vapor pressure lowering in the surrounding tuffaceous rock. Results indicate that the vapor pressure of water droplets is not significantly increased above the saturated vapor pressure of freestanding water when the droplet size is greater than 100 mu m. However, if the relative humidity of the surroundings is exactly equal to 1 or if the droplet radius is very small (<1 mu m), the effects of interface curvature will enhance the evaporation of water droplets. Finally, expressions are developed to determine the minimum liquid flux required to propagate flow through either a single fracture or a network of fractures without being evaporated.

AN - 79382862; 9378660 AB - DOE facilities are required to conduct environmental surveillance to verify that facility operations are operated within the approved risk envelope and have not caused undue risk to the public and the environment. Given a reduced budget, a strategy for analyzing environmental surveillance data was developed to set priorities for sampling needs. The radiological and metal data collected at Sandia National Laboratories, New Mexico, were used to demonstrate the analysis strategy. Sampling locations were prioritized for further investigation and the needs for routine sampling. The process of data management, analysis, prioritization, and presentation has been automated through a custom-designed computer tool. Data collected over years can be analyzed and summarized in a short table format for prioritization and decision making.

Roughly 25% of Superfund groundwater remedies in 1995 involved some type of monitored natural attenuation, compared to almost none 5 years ago. Remediation by natural attenuation (RNA) requires clear evidence that contaminant levels are decreasing sufficiently over time, a defensible explanation of the attenuation mechanism, long-term monitoring, and a contingency plan at the very least. Although the primary focus of implementation has to date been the biodegradation of organic contaminants, there is a wealth of scientific evidence that natural processes reduce the bioavailability of contaminant metals and radionuclides. Natural attenuation of metals and radionuclides is likely to revolve around sorption, solubility, biologic uptake and dilution controls over contaminant availability. Some of these processes can be applied to actively remediate sites. Others, such as phytoremediation, are likely to be ineffective. RNA of metals and radionuclides is likely to require specialized site characterization to construct contaminant and site-specific conceptual models of contaminant behavior. Ideally, conceptual models should be refined such that contaminant attenuation can be confidently predicted into the future. The technical approach to RNA of metals and radionuclides is explored here.

This well was part of Sandia's program to evaluate slimholes as a geothermal exploration tool. During and after drilling the authors performed numerous temperature logs, and at the completion of drilling attempted to perform injection tests. In addition to these measurements, the well's data set includes: over 4,000 feet of continuous core (with detailed log); daily drilling reports from Sandia and from drilling contractor personnel; daily drilling fluid record; and comparative data from other wells drilled in the Newberry KGRA. This report contains: (1) a narrative account of the drilling and testing, (2) a description of equipment used, (3) a brief geologic description of the formation drilled, (4) a summary and preliminary interpretation of the data, and (5) recommendations for future work.

The initiation of pitting of aluminum in water vapor and chlorine environments has been associated with the adsorption of chloride ions on the surface of oxidized aluminum. The authors present a method for calculating the minimum energy configurations of atomic and molecular species adsorbing on defected solid surfaces in the presence of an electrolyte. The method couples a quantum region containing the adsorbing atom or molecule and neighboring lattice atoms to a continuum which may contain a real charge. A molecular surface surrounds the quantum zone, discretized into boundary elements facilitating the coupling of the Schroedinger and Poisson equations. The interfacial polarization created by the electrons in this zone, (from the Poisson equation using Green's functions) is incorporated into the Hamiltonian providing a reaction field for the next iteration quantum calculation. Lattice defects induce single and double layers of charge at the interface, treated as additional background charges in the Hamiltonian. The authors find that these polarization effects can reduce the binding energy of the Cl (super (-) ) and that a charged defect can displace the minimum and well depth of an adsorbing Cl (super (-) ).

The models have been generated for a majority of the unsaturated and shallow saturated zone within an area referred to within the Yucca Mountain Site Characterization project as the site area. They comprise a number of material properties of importance both to detailed process-level modeling activities and to more summary-style performance assessment modeling. The material properties within these models are both spatially variable (heterogeneous) and spatially correlated, as the rocks are understood from data obtained from site-characterization drill holes widely scattered across the site area.

This assessment included determining field concentrations of cesium 137 ( (super 137) Cs) and other inorganic contaminants and modeling of the flow and transport of the liquid waste that was sent to the drain field. The field investigation detected no contamination deeper than 15 feet (4.6 m) from the bottom of the drain field. Prediction of the water content of the vadose zone showed no saturated conditions for times greater than 10 years after the known infiltration. Sensitivity analysis of the modeling parameters showed the equilibrium sorption coefficient to be the most important factor in predicting the contaminant plumes. Calibration of modeling results with field data gave a (super 137) Cs sorption coefficient that is within the range of values found in the literature. The risk assessment for the site showed that the contamination poses no significant risk to human health. Copyright 1997 by the American Geophysical Union.

The 30 kW electron beam test system at Sandia National Laboratories was used to sweep the beam spot along one direction at 1 Hz. This produces a localized temperature `spike' of 750 degree C for each pass of the beam. Large thermal stresses in excess of the yield strength are generated, due to very high spot heat flux, 250 MW m super(-2). Cyclic plastic strains on the order of 0.6% produced visible cracking on the heated surface in less than 3000 cycles. An in-vacuo fiber optic borescope was used to visually inspect the beryllium surfaces for crack initiation. Grades of US beryllium tested included: S-65C, S-65H, S-200F, S200F-H, SR-200, I-400, extruded high purity, HIP'd spherical powder, porous beryllium (94 and 98% dense), Be/30% BeO, Be/60% BeO, and TiBe sub(12). Russian grades included: TGP-56, TShGT, DShG-200, and TShG-56. Both the number of cycles to crack initiation and the depth of crack propagation, were measured. The most fatigue resistant grades were S-65C, DShG-200, TShGT and TShG-56. Rolled sheet Be (SR-200) showed excellent crack propagation resistance in the plane of rolling, despite early formation of delamination cracks. Only one sample showed no evidence of surface melting, Extruded (T). Metallographic and chemical analyses are provided.
